Top 10 Heaviest Metal Bands

This list is not a list of the "best" metal bands, but the "heaviest" metal bands. This is the best of the "heavy" ones. The "ingredients" used include: Quality of music, style, skill, and how well you can bang your head to it.
The Top Ten
1 Cannibal Corpse Cannibal Corpse is a American death metal band from Buffalo, New York, formed in 1988. The band is known for their graphic album covers, explicitly violent lyrics and song titles like "I C** Blood" The group got into mainstream after performing the song "Hammer Smashed Face" in the 1994 film Ace Ventura: Pet Detective. In 1995, vocalist Chris Barnes left the band to focus on his new death metal project Six Feet Under. He was replaced by George "Corpsegrinder" Fisher of the band Monstrosity, who has remained as the frontman since. more.

Cannibal Corpse is the most hardcore, aggressive, and kick ass band I have ever heard. I enjoy many of the bands above but they are no where near as hardcore as Cannibal Corpse. This is one of the rare bands you find that can sound like they do. Bands like bring me the horizon and peirce the veil do not even need to be close in the ranking, as they are not hardcore, and are not the best bands out there. This band knows how to scream and make riffs, unlike so many other bands

Cannibal Corpse is the most hard-core heaviest and one the best band of all time. Look at their album covers... It gross, and kind of creepy but awesome. And even the lyrics are so gross, violent and aggressive making a perfect death metal band and even the heaviest band

Just look them up on iTunes and read the names of all of their songs on the "butchered at birth" and "tomb of the mutilated album. The names of their songs are absolutely HORRIFYING sodomy-filled lyrics are enough to make them the heaviest.

YES. Cannibal Corpses sound is heavier than Metallica and slayer combined. Yes cannibal Corpse is the heaviest. Here are some examples. Tomb of the mutilated, vile, evisceration plague, KILL, eaten back to life and very heavy songs.

2 Slayer Slayer is an American thrash metal band from Huntington Park, California, formed in 1981 by guitarists Jeff Hanneman and Kerry King. They rose to fame with their 1986 album Reign in Blood, and is credited as one of the big four of thrash metal bands, the others being Metallica, Megadeth, and Anthrax. more.

Slayer realeased some of the heaviest albums of all time such as Reighn in Blood and Seasons of the Abyss. Even their name just screams heavy band. I personally find them heavier than Cannibal Corpse because I find that E, Eb, and D/Drop D are the heaviest tunings (the most common thrash tunings) and that Slayer's vocals are just the right range to be heavy. Many people would disagree, but it's an honest opinion. I find some Cannibal Corpse songs heavier than others, but I think Slayer just beats them out.

If you disagree that they are heavy, just listen to Angel of Death or Raining Blood loud through good sound equipment, and feel the music crushing you.

Slayer may be "heavier" band than Metallica, but they all represent the same time era of being created. There will be time when Slayer, Metallica, Megadeath and all together will be satanic stories for the kids, and there will be the time when these are "hippy" proge metal. To me Slayer is more like faster style trash metal than Metallica, while Metallica is deeper and heavier... But to get the hippies to leave the premises I would choose Reign in Blood over Enter Sandman.

Slayer should definitely be # 1. Come on guys... This band has produced the riffs that are traditionally metal and has been loved all across the globe... and what about the drums? They're ferocious especially the double basses... Slayer haters and asss do listen to Angel of death, Raining blood...

It is now a battle between Metallica and Slayer. Yes Metallica is extremely heavy, Master Of Puppets, Ride The Lightning yet if you listen to Reign in Blood and World Painted Blood, you will see Slayer is heavier than Metallica.

3 Behemoth Behemoth is a Polish blackened death metal band from Gdańsk, formed in 1991. They are considered to have played an important role in establishing the Polish extreme metal underground.

Behemoth isn't called by some "The Kings Of Black Metal" for no reason. They're one of the only actually good blackened death metal bands, the combo of the extremely heavy elements of Death metal and the evil sounding noisiness of Black Metal is rarely this perfect.

Come on guys, this list is not bout voting for yer favorite band.. My favorite metal band is lamb of god and pantera and not to mention I'm not a very big fan of behemoth but I have to agree their music are extremely heavy take slaves shall serve for example, the song itself sounded like it want to kill you

Have you already heard "Slave Shall Serve"? "He Who Breeds Pestilence" maybe? No? Then go and check most heavy band in existence. Sure - there is more mainstream stuff like "Cannibal Corpse" or more 8th empty string 0-0-0-0-0 like "Meshuggah", but this one is true hell, and in artistic way also.

Behemoth are one of my favourite bands. This list is basically all the well known bands. I haven't even seen nile on the list and behemoth/nile are so much heavier. And the people who voted deathcore bands like BMTH are posers who don't know real metal

4 Nile Nile is an American technical death metal band from Greenville, South Carolina, United States, formed in 1993. Their music and lyrics are inspired by Ancient Egyptian/Near Eastern mysticism, history, religion, and ancient art, as well as the works of H.P. Lovecraft.

This is a popularity contest. Nile is way heavier than all these other 9 bands, Cannibal Corpse deserves to be on the list, not the other 8. Dying Fetus, Misery Index, Mortician, Malevolent Creation, Suffocation, Carcass, Beheaded, Morbid Angel. All those bands should be here. Not those other bands that are mentioned. People just don't know what heavy is or they are completely uneducated when it comes heavy music

Metallica, Pantera, Slipknot and Black Sabbath in the Top 10? Even Slayer is way too light compared to Death or Black Metal.
Brutal Death Metal like Nile is pretty much one of the heaviest music types you can find out there.

Annihilate the wicked on this page. Nile is amazing band who really understand technical death metal. Enough said and those who think a musically oblivious 8th graded is voting well I am musically smart 9th grader

Nile is by far the heaviest band in the world. In instrumental plan and also the atmosphere they are bringing. All other aren't come close

5 Meshuggah Meshuggah is a Swedish progressive metal band from Umeå, formed in 1987. They are often considered the fathers or founders of the djent metal sub genre due to their use of downtuned guitars. They are also known for their song “Bleed”, which is known for its extremely complicated instrumentation, especially the drumming. They released their most recent album, “The Violent Sleep of Reason” on October 7th, 2016. Meshuggah's line-up consists of founding members vocalist Jens Kidman and lead guitarist Fredrik Thordendal, drummer Tomas Haake, who joined in 1990, rhythm guitarist Mårten Hagström, who joined in 1992 and bassist Dick Lövgren since 2004.

Not much explanation here, it's meshuggah. They were playing djent like 30 years before it existed. The combination of prog djent death metal has never sounded so good. The guitar tuning is so low it's probably in hell by now. That and having a tractor on the drums and yelled vocals are enough to give someone an anxiety attack.

Not only is Meshuggah's tone and overall vibe by far the heaviest on this list, their lyrics push the bar to a whole new level of dark poetry. There couldn't be a stronger juxtaposition between the whiny, insipid lyrics of many "core" bands splattered with unnecessary F-shots, and the rich imagery and hellishly uncanny lyricism found in Meshuggah.

This band is definitely the heaviest on the list. Most bands you'll hear at least one or two songs in an album that aren't as heavy as the others, sometimes more. However, Meshuggah only makes heavy music, and, to me, is the heaviest sounding band I've ever heard.

ObZen, and Chaosphere are the best albums made by these technical masters. Just think! With Fredrik Thorndendal with his heavy and atmospheric guitar solos, and Tomas Haake with his complex heavy drumming, Meshuggah is one of the best technical modern heavy metal bands of our time!

6 Metallica Metallica is an American Heavy/Thrash Metal band formed in 1981 . The original lineup was James Hetfield (Vocalist and Rhythm guitarist), Dave Mustaine (Lead Guitar), Lars Ulrich (Drums), Ron McGovney (Bassist). The group came into mainstream from their Self-Titled album and the hit single "Enter Sandman".

With their first two albums, Kill 'Em All and Ride The Lightning reaching underground success, their third effort, Master of Puppets has since become one of the most important heavy metal albums ever, as it became the first thrash metal album to be certified platinum. The title track has since become the band's most played song live. more.

My vote goes to these guys. Death Metal and Black Metal bands are more noise than heavy. Slayer is really fast and aggressive, but Metallica came up with some of the heaviest riffs ever in the 80s, fast AND slow. If you don't think they are heavy, listen to Fight Fire With Fire, The Thing That Should Not Be, Battery, Harvester of Sorrow, Damage Inc, Dyers Eve, Blackened, For Whom The Bell Tolls, and Trapped Under Ice. When you're done, show me proof they aren't heavy.

Music in general is very subjective. It is all about the person listening the song etc. But briefly to the point: Metallica, within their time as categorized as "heavy metal" the band made their Black/Metallica album. It is, and still is very, very heavy, to the sound, feel and how it is performed.
Yes, it was produced very well. It has many good songs, even so good that they could be thought to be made as simply in purpose of making money... or just to make sure that future kids have some tunes to play to their chicks.

Sad But True is a good example of very heavy song as musically. There are much, faster, slower, deeper, lover - what so ever bands/songs there. I would love to challenge Dimmu Borgir, Cradle of Filth and Moonspell to make a cover song of Ozzy's Mr. Crowley... Oh wait... They are "heavier", why shouldn't/couldn't they make cover of Enter Sandman? - They could, but they don't want to?

In the end, we can go back in the history towards the great classical ...more

Well, firstly let's put their post... AJFA albums aside. Consider their first four masterpiece albums. Pretty heavy eh, Metallica haters? They were easily the heaviest back in the 80s along with Slayer. James had a amazing voice which goes well with their songs. They have original riffs unlike those recycled ones by Slayer. I don't think Maiden should be in the top ten, yeah they're amazing but not that "heavy". A7X are a joke they shouldn't even be remotely close to the top ten. And where the hell are Black Metal bands like Gorgoroth and Mayhem?

If you say they aren't heavy at all, you aren't a metalhead. At all. Listen to that Slayer isn't heavy when they palm mute. When Metallica palm mute, they are. Heck, The Thing That Should Not Be has a riff that slam bands would use! Fight Fire With Fire, Battery, and Dyers Eve have some difficult and fast riffing, which is what death metal is made of.
Go listen to The Thing That Should Not Be, Fight Fire With Fire, Battery, and Dyers Eve as loud as you can and go tell me they're not heavy!

7 Pantera Pantera was an American Heavy Metal band formed in 1981 by guitarist Dimebag Darrell and drummer Vinnie Paul. The band started out as a Glam Metal act in the 1980s with little success. After discarding their original lead vocalist and enlisting Phil Anselmo, the band signed a major record deal with Warner Music Group via Atco Records. Around this time, Pantera would undergo a major change in their musical direction, discarding their Glam Metal image in favor of a more more Thrash Metal esque reputation. Their Thrash influences would eventually be seen as influences for Groove Metal more.

Although the list is messed up, pantera would definitely be the heaviest of the bands mentioned in the top 10. Listen to 5 minutes alone, god that song is heavy! One of the heaviest riffs ever made in the history of metal, no song I have heard can match up to the heaviness of this song. And trust me, I listen to a lot of metal.

This list is lying. Pantera are OBVIOUSLY heavier than Metallica, Slayer, and pretty much every other band ever (except for MAYBE Cannibal Corpse)! Don't believe me? Here's my proof:

Cowboys from Hell
Vulgar Display of Power
Far Beyond Driven
The Great Southern Trendkill (especially this one, it's the best metal record of all time right up there with Pantera's previous two efforts)
Reinventing the Steel

Listen to all of these (in order), and I guarantee you will think that I am right. If not, then that's fine, it's probably just because Cannibal Corpse out-heavies them by just a little bit...

These "musicians" should be number 1. I quoted musicians because they aren't musicians. They're beasts. Their music isn't the fastest, but they have Dimebag's signature sound, Vinnie Paul's amazing grooves, Rex's pounding bass, and Phil's skull crushing screams.

Strength beyond strength. You don't need 7 strings, blast beats, and pure growling to be the heaviest band in the world. Pantera proved that with their sheer aggressive anger and pure power. Pantera is the heaviest band of all time!

8 Infant Annihilator Infant Annihilator are an English/American deathcore band based in Hull, East Yorkshire. The band was formed in 2012 by drummer Aaron Kitcher and guitarist Eddie Pickard.

Friggin amazing. Deathcore at it's finest. Between Infant Annihilator and Suicide Silence, I can't tell which is heavier, probably this. BONUS: They're Bri'ish

The heaviest band on the planet. If you don't believe me, listen to the album "The Palpable Leprosy of Pollution". "Pinned Down and Fisted" has the most intense rift I've EVER HEARD.

Heaviest band I know. Just look at the lyrics and listen to the sheer brutality.
Don't know what people have against deathcore. It's just as heavy or heavier than death metal. Maybe it's the way the people in the bands look. Or maybe death metal fans are jealous of the success of bands like suicide silence. Check out the band Callenish Circle

I'm sorry but Slayer sound like nursery rhymes compared to this... The guitars, drumming, vocals, heck even the lyrics are heavier. I was going to pick cattle decapitation... but due to the lyrics I decided on IA

9 Anaal Nathrakh Anaal Nathrakh are a British extreme metal band formed in 1999 in Birmingham, England. They are currently signed to Metal Blade Records.

Musically, nothing really competes against Anaal Nathrakh in regards to heaviness. Black Metal with strong influences of Grindcore and Industrial Music, its an effective combination to establish something uniquely heavy, which this band succeeds. In fact, the music is so chaotic, even bands like Cannibal Corpse sound rather mellow in comparison.

Heaviest band ever. Castigation and Betrayal is the most unfairly heavy song ever, 30 seconds of extremely heavy doom metal, 3 minutes of insanely aggressive death metal, and back to those 30 seconds. That song alone makes them the heaviest band ever, not to mention Pandemonic Hyperblast is the second heaviest song ever, behind that.

I think they should be number one honestly. They're basically the total annihilation of mankind in music form. Just listen to tracks like "I Am The Wrath Of Gods And The Desolation Of The Earth" and you'll see what I'm talking about.

Maybe not the absolute heaviest band ever, but definitely the heaviest band with clean choruses, and aside from maybe Meshuggah and Cattle Decap they are clearly much heavier than anything else in the top 10.

10 Cattle Decapitation Cattle Decapitation is an American Deathgrind band from San Diego, California formed in 1996. Cattle Decapitation's songs protest the mistreatment and consumption of animals, the abuse of the environment and touch subjects such as misanthropy and genocide of the human race. Much of their music is based on putting humans in the situations that animals are subjected to, for example animal testing, slaughter, etc. While the band started with an entirely vegetarian lineup, only two current members are vegetarian namely Travis Ryan and Josh Elmore.

Bands that can get really heavy:

Popular bands:
Slayer, Metallica, Pantera, Slipknot

Black/death/core/grind bands:
Cannibal Corpse, Anaal Nathrakh, Cryptopsy, Devourment, Behemoth, Nile

Other extreme bands:
Sodom, Kreator, Sepultura, Morbid Saint, Dark Angel, S.O.D, Gojira

Slow bands:
Black Sabbath, Candlemass, Black Tongue

Yeah, those bands can get super heavy. Fight Fire With Fire by Metallica is an example of one of the heaviest ever, so is Heretic Anthem by Slipknot, March of the SOD by S.O.D, Disciple by Slayer, Mourners Lament by Candlemass, and God Is Dead by Black sabbath. And most of the black/death/core/grind songs.

But NONE of them come close to Cattle Decapitation. The Carbon Stampede is like the heaviest song in the world. They make Cannibal Corpse sound like silence.

It's so impossible to be heavier than this! Nothing comes close to Forced Gender Reassignment or Carbon Stampede. God, the entire Monolith Of Inhumanity album is just full of chaos!

Honestly, when people think that Slipknot is heavier than Cattle Decapitation, they do not deserve to be called metalheads. This band has it all. Lyrics with an actual meaning (not just melodramatic, pseudo-angry nonsense), mean riffs, insane drumming, and by far the most diverse vocalist in all of modern metal.

I would have to say, Slayer is pretty damn heavy (and my favourite metal band ever) but they would have to be the 2nd heaviest under Cattle Decap. Man, this band is brutal!

The Contenders
11 Death Death was an American death metal band formed in 1983 by Chuck Schuldiner. Death is considered to be one of the most influential bands in heavy metal and a pioneering force in death metal. Its debut album, Scream Bloody Gore, has been widely regarded as the first death metal record, while the band's driving force, Chuck Schuldiner, is acknowledged as the "Godfather of Death Metal." Death released 7 studio albums, and are the band that started the Florida Death Metal scene. They were known for their death metal classics Lack of Comprehension and Crystal Mountain. Death ended in 2001 when Schuldiner died of Brain Cancer.

Some people don't know the definition of heavy. Were talking chunky riffs, layered raw sounds, relentless tempo, growling vocals and technicality here. Not popular bands and certainly not nu metal!

Death is the final form of metal music development. It is the absolute. Without any posing or heavy for the sake of sounding heavy. It's raw, melodic and metal as it gets. It is metal in its pure form.

Death! In my opinion one of the best and first bands in real death metal their old school sound is much heavier than nu metal!

How is slayer, and Metallica above this? This is heavier and more intense.

12 Lamb Of God Lamb of God is an American heavy metal band from Richmond, Virginia. Formed in 1994, the group consists of vocalist Randy Blythe, guitarists Mark Morton and Willie Adler, bassist John Campbell, and drummer Chris Adler.

Lamb of God is heavier than most bands, but there's no need to compare them with extreme Thrash Metal (such as Slayer) or BDM (such as Cannible Corpse) even some Deathcore (if you considered deathcore as metal). There are two reasons:1, LOG's music, mostly, are slow, or at mid-tempo. 2, They have pretty melodic riffs. Rate the Bands for their heaviness, If Cannible Corpse and Slayer are at 10, the Beatles at 1, I think LoG should be around 7.5.

I love Black Sabbath. With that said, no other band besides Meshuggah should be on this list with Lamb of God. The first Slipknot album was decent, Metallica isn't half bad, and I do enjoy Pantera. Cannibal Corpse is a total joke, so there's that. The rest, I can totally do without. Especially on a "Heaviest Bands" list. Seriously, what.

Lamb of God is amazing. Nobody does vocal like randy Blythe. He kicks ass, their material is amazing and everything they have is kick ass, heavy, bad ass, and metal as HELL! They are heavier then half the bands on this list and although they aren't they heaviest ever, they are without a doubt one of the best ever!

Sorry guys, this list is about "heaviest, " not which bands your girlfriend or mom can tolerate. Therefore, as cool as they are, Mettallica, Black Sabbath, Megadeth, Maiden, have no business appearing here. When I think heavy, I think of condemnation of my soul, bleeding ears, and pits with broken bones... And Lamb of God.

13 Decapitated Decapitated is a Polish technical death metal band formed in Krosno in 1996. The group comprises guitarist, founder and composer Wacław "Vogg" Kiełtyka, vocalist Rafał Piotrowski, bassist Paweł Pasek, and drummer Michał Łysejko.

Very technical, fast and heavy death/groove metal band. If you think Cannibal Corpse is either too gruesome for you or your a Meshuggah and Slipknot fan you'll easily get into these guys. System of a Down is hard rock and CoF is mall core. What's next, Bathory being heaviest on this list? I hope not.

14 Dying Fetus Dying Fetus is an American death metal band originally from Upper Marlboro, Maryland. Formed in 1991, the group is known for their consistently hook-laden song structures, characterized by blast beats, complex riffing, slam riffs and heavy breakdowns.

Powerful drums, speed, low tuning, brutal vocals. Dying Fetus is the definition of heavy. This should be number one on the list without a doubt.

This and Infant Annihilator are the Heaviest bands I listen to.

The name and the music... Says it all.

Heaviest and the best

15 Separatist

I kid you not...these guys should be in the top seriously why are bands like slipknot, iron maiden and Metallica high up on this list? No hate to them but this list is for the HEAVIEST bands. "Isolation" by separatist is one of their songs that prove they are worth being put at a higher rank on this list.

16 Infernal War Infernal War is a Polish black metal band formed in Częstochowa in 1997. The band is known for their extreme anti-christian and WWII lyrics, leading them to be mislabeled as a NSBM band. Critics describe the band as "brutal black metal."

Basically Nile but more raw and less technical.

17 Black Tongue

Yo this list is so inaccurate. Black Tongue is heavier than nearly every single band above them on this list

Their slow and doom-core like style makes them heavy and brutal.

This band is so heavy. Mixed with Deathcore and Doom Metal.

By far the heaviest band of all time.

18 Cryptopsy Cryptopsy is a Canadian technical death metal band from Montreal, Quebec, formed in 1988. The band has sold over 300,000 records.

How are these guys so low? Graves of the fathers is the heaviest song in existence, and that's just one song. The whole none so vile album is soul crushing

Cryptopsy, Cattle Decapitation and Periphery need to be higher.

Their album "None So Vile" is probably the heaviest death metal album ever

19 Broken Flesh

How is Led Zeppelin even on this list. You might as well put Justin Bieber on here too.

20 Strapping Young Lad Strapping Young Lad was a Canadian extreme metal band formed by Devin Townsend in Vancouver, British Columbia in 1994. The band started as a one-man studio project; Townsend played most of the instruments on the 1995 debut album, Heavy as a Really Heavy Thing. By 1997, he had recruited permanent members; this line-up, which consisted of Townsend on vocals and guitar, Jed Simon on guitar, Byron Stroud on bass, and Gene Hoglan on drums, lasted until the band's dissolution.

This appears to be a popularity contest, rather than what is really "heaviest". Love slayer, slipknot... Etc but nothing can compare to SYL (except maybe meshuggah) for heaviness.

Stop what you're doing. Go and listen to 'Oh My God' by Strapping Young Lad. Come back and vote then.

How Strapping Young Lad is not the first of the list is beyond my comprehension.

Listen to "Oh My God" and "Happy Camper" then come back and vote correctly.

21 Nails Nails is an American powerviolence band formed in 2009 in Oxnard, California. The band has achieved a cult fanbase and is very well received by fans of grindcore and death metal. Nails is currently signed to Nuclear Blast.

If you don't agree with Nails being top choice, I guess You Will Never Be One of Us.

You haven't heard heavy until you heard of these guys.

Every single song is a facemelter. You haven't heard heavy till you've heard these guys

22 Iron Maiden Iron Maiden are an English Heavy Metal band formed in Leyton, East London, in 1975 by bassist and primary songwriter Steve Harris. The most critically acclaimed period for the band was from 1983-1989. With vocalist Bruce Dickinson, bassist Steve Harris, lead guitarist Dave Murray, rhythm guitarist Adrian Smith, and drummer Nicko McBrain. Smith left the band in 1989 and was replaced by Janick Gers. But returned in 1999, and now the band has three guitar players. more.

GREYBOYY seems to know very little about Heavy Metal and is citing bands that just use speed and relentless noise to quantify what is 'Heavy'. For volume to have impact there must also be silence in the music. How can you seriously be discounting bands that are responsible for creating Heavy Metal in the first place? Maiden are a Heavy Metal band (How can this band NOT be in the top 30? ). Priest is a Heavy Metal band. Sabbath are a Heavy Metal band. Metallic are a Heavy Metal band. Heavy does not equal constant racket and growling tuneless vocals.

Black Sabbath has nothing to do with extreme metal, it's a classic blues-rock band, then it became a hard rock/heavy metal band, Metallica and megadeth have some heavy songs, but there are much pop metal bands, Slayer is among the heaviest, but Iron Maiden are more melodic and with complex songs, and with much better vocalist!

Iron Maiden? Heavy? Seriously? This band is awesome but when it comes to heaviness Iron Maiden has no place even in the top 30!

Ridicilous! Everybody know what Iron Maiden is the heaviest band of all times! No one could compare, no one could even stay close to Iron Maiden!

23 Slipknot Slipknot is an American metal band formed in Des Moines, Iowa in 1996. The band is best known as one of the pioneers of the New Wave of American Alternative Metal during the late 1990s - 2000s and are distinguishable by the band's clothing choices, consisting of black/red jumpsuits and horror inspired masks. more.

I love Metallica and Slipknot and I'm okay with Slayer but Metallica was the true heavy metal in the 80s like For Whom the Bells Toll and Master of Puppets! But Slipknot is a very heavy metal band, dark lyrics, Corey's vocals, the down toned of guitars, and the masks. Metallica has gotten softer slipknot is getting more harder and awesome. I mean they weren't what they were like in Iowa and Subliminal Verses but they said the next album is darker than Iowa and Subliminal combined! Their darkest songs are Eyeless, People=S***, and Heretic Anthem. Well to me, MAGGOTS FOR LIFE

The heaviest bands are mostly black and death bands, but in terms of popular bands, they are the heaviest. All Hope Is Gone is a death metal and thrash metal song, so is Gematria, Sarcastrophe, Eeyore, Three Nil etc. But the Iowa album, that is the heaviest of all. Disasterpiece is so heavy.

I love slipknot and when I get older I will show my children this band. When I first heard of slipknot I was already addicted to it... I found after slipknot, betraying the martyrs and I love them too. Then after them I found dead by April... Their music sounds a little like dubstep n the beginning and I love them. The first song I heard by slipknot-psychosocial
Betraying the martyrs- let it go
Dead by april-beautiful nightmare
Also I like black veil brides and the first song I heard by them was in the end... Mine and my girlfriends song by them is rebel love song but ita not really metal

Slipknot are actually still very heavy. Maybe not as heavy as Meshuggah or Cannibal Corpse, but still very heavy. People who don't say they're heavy, go listen to People = S***, Psychosocial, Disasterpiece etc. They are 10 billion times heavier than Black Sabbath, A7X, Metallica, Deep Purple. While they do have some ballads (Snuff, Till We Die etc.) Most of their songs are HEAVY, and the vocals are pretty brutal.

24 Megadeth Megadeth is an American thrash metal band from Los Angeles, California. Megadeth was formed in 1983 by guitarist Dave Mustaine and bassist David Ellefson, shortly after Mustaine was fired from Metallica. They have released 15 studio albums to date, and have gone through many lineup changes, with Dave Mustaine being the sole constant member.

They released their debut album “Killing Is My Business...And Business Is Good!” in 1985, but became successful after the release of “Peace Sells...But Who’s Buying?” in 1986. more.

This band is just as heavy as Metallica... Metallica is not that heavy compared to any death metal, black metal, or doom metal band. Especially funeral doom metal bands.

Metallica's heavy? Heavier than Megadeth and Lamb of God and Slayer? Ha Ha. Really, there should be some sense among people. Come on.

Still rocking after all these years. Better than the rest. Enough said. From Killing is My Business to Super Collider, better quality.

Megadeth is heavier than Metallica and avenged sevenfold. I love Iron Maiden but Megadeth is heavier than them too.

25 Deicide Deicide is an American death metal band formed in 1987 by bassist and vocalist Glen Benton and drummer Steve Asheim. They are known for their blasphemous and satanic lyrics which have resulted in bans, lawsuits and criticisms from religious groups and the public. Frontman Glen Benton is also known for more.

This should be higher then Metallica, Iron Maiden, Megadeth, and especially Black Sabbath.

Deicide rule the world!
