Top Extreme Metal Genres

Extreme metal is a term for a number of related heavy metal subgenres that have developed since the early 1980s. This list includes extreme metal subgenres and fusions between same extreme metal subgenres or between other genres.

The Top Ten

1 Death Metal

So much diversity within its subgenres and the amount of experimentation. This is what defines extreme metal as well as the complex song structures and intricate riff patterns.

Death Metal is the heaviest metal genre and the second is Black Metal.
Death Metal is heavier than Black Metal, because Death Metal is
1. Harder
2. Faster
3. Lower
4. Technically difficult
5. Mighty
6. Growling is heavier than screaming
PS Black Metal is the Evilest!

I don't think it is, a version of death metal is, brutal slamming death metal, death metal itself is in no way the heaviest subgenre

Death is the definitely the heaviest genre, Please explain why Thrash is number 1? There is no ways that thrash can be heavier than death metal.

It doesn't say "Heaviest Extreme Metal Genre", it says "Top Extreme Metal Genre".

2 Thrash Metal Thrash Metal is a Heavy Metal subgenre developed during the early 1980s and an early precursor of Extreme Metal. Thrash Metal features a faster and more aggressive guitar work than Traditional Metal with shredding and double-bass drums and can range from melodic singing to loud shouts. more.

Demolition Hammer, Sepultura, Coroner, Dark Angel, Kreator, Sodom, Overkill, Exodus, Slayer... can it get better?

Thrash metal, doom metal, death metal, melodic death metal, black metal and grindcore are the only genres that should even be here. Stuff like power metal, groove metal and metalcore don't belong on this list because they aren't "extreme" metal genres. The fact that nu-"metal" is here is laughable.

Kreator, Testament, Overkill, Metallica, Mantic Ritual, Tankard, Sodom, Holy Moses, Destruction, Sepultura, Annihilator, Slayer, Megadeth, Anthrax,...
Just because Thrash has the most epic bands out there!

Started em all, old school thrashers by far the most talented and they didn't feel the need to dress up like vikings and sing like the cookie monster

3 Black Metal

When you want to listen to a band you can't find on spotify because it's too extrmeme. Some of these bands are actually banned from preforming because they SACRIFICE LIVE GOATS ON STAGE AND RIP THEIR ORGANS OUT. If that's not awesome, I don't know what is.

Why is there a guy who seems to think symphonic black metal is heavier than black metal and makes lists with made up genres such as "Nu extreme metal"? Anyway, black metal is the most "extreme" genre in my opinion because not is only the music is very inaccessible, but the violence and Satanism that occurred during the second wave hasn't really been seen in any other metal genre.

This genre is the bad apple of the metal tree. Bands like Mayhem and Gorgoroth give other metal music listeners a bad name by the bands being satanist and the retards at the music industry and all other music genre fans think metal is for satanist emo teens!

Death metal is the heaviest, but I will vote this in order to attempt to topple thrash. Thrash is not an extremely heavy metal genre.

4 Melodic Death Metal

Veil Of Mya all the way on this one. Mikasa and Doublespeak. Good stuff.

A number of these aren't even extreme metal. Metalcore, crossover thrash and (kinda) doom shouldn't be on here. Also, progressive death metal and technical death metal are the same thing, just different names.

No, tech death and prog death are different, they just overlap very often

How can anyone not love bands like Insomnium, Arch Enemy, Noumena, and Wolfchant?

Very abiguous genre. There are so many different types of Melodic Death.. While I love bands like Insomnium, Be'Lakor, Carcass, At The Gates, Persefone, Quo Vadis, Intestine Baalism etc., there are also many many bands I dislike, who are considered as one of the best and genre-leading ones.
But still. I enjoy the gems of this genre, and I guess that's all that counts in the end.

The bands you mentioned are defining melodic death, CoB and Omnium gatherum are also good, but honestly insomnium is better than omnium in my opinion.

5 Doom Metal

Not my favourite metal genre, but definitely the most extreme, especially funeral doom and drone metal

Easily the heaviest genre. People like fast metal, but there's nothing like the MASSIVE sound of Doom. It's the closest "modern" genre to bands like Black Sabbath. How can that be a bad thing? I love faster metal like thrash and death metal, but there's nothing quite like the sheer heaviness of doom. It gives you this "trudging through mud and sludge" kind of feel. Music is about feel, not super technicality (that doesn't hurt though), and Doom definitely has a very unforgettable feel to it. It's like being crushed with a massive wall of sound, and I love it.

Love doom. Should be above thrash at least, but I still think black and death metal deserve to be above doom metal even if I prefer doom metal myself.

You don't need to be fast to be heavy

To be extreme, you need to be fast and aggressive. Which doom isn't. Doom is mostly dark but not extreme.

6 Blackened Death Metal

Black metal plus death = something heavy

Behemoth are awesome!

BEHEMOTH! At the left hand ov god is my second fave song after hammer smashed face

Blackened Death Metal has got some of the heaviest drumming ever.
Drummers like Inferno of Behemoth and Marthyn of Belphegor take it to the next level.

7 Technical Death Metal

Any song from the Doom 2016 OST by Mick Gordan is good Technical Death Metal.

NO, Technical Death metal and Progressive Death metal is NOT the same. Opeth are progressive but not technical. Nile are certainly technical but not much progressive. In rare cases a band can be both - Obscura are both technical and progressive. Also read the comment by Flav who says the same.

Technical/Progressive, though some Technical/Progressive Death Metal bands like "Nile" play it more brutal.

Progressive death metal and technical death metal are the same thing.

Technical Death Metal = Progressive Death Metal, same about Black Metal, see Emperor's page on wikipedia or All Music review of their last album.

8 Grindcore

Grindcore is among the most progressive and harsh musical styles of all time for me. Its unsympathetic, abrasive songwriting style and harsh, brutal instrumentation puts it up at the top of my list.

Grindcore is the most violent and the heaviest genre in the world in my opinion.

Grindcore is simply the end of all things extreme, the intensely downtuned guitars and blasting drums there's nothing that tops grindcore, not even death metal. For any confirmation listen to Brutal Truth - Birth of Ignorance. Grindcore is a wall of brutality and it's brilliant.

More harsh and abrasive than Death Metal. Only Tech Death comes close to Grindcore's brutality.

9 Deathcore

This should be the number one heaviest genre of metal. It has everything that Death has + breakdowns, chugging and more blast beats

This isn't metal guys, this is the punk version of death metal. It's extreme punk.

The dynamic of going really fast to really slow and sludgy makes deathcore feel more intense than death metal, that's just my opinion and feeling of course.

My feeling is that the abusing of breakdowns ruins it completely. I'm not a fan of the vocal style either.

Infant Annihilator, Thy Art Is Death, Born of Osiris, White Chapel, BMTH(2004-2008) are all a part of Deathcore and they really show they're own brutal way of anger and other emotions

10 Groove Metal

Why is this not in the top ten? It can be as heavy and extreme as thrash but slowed down. Bands like Machine Head, Lamb of God, Pantera, Five Finger Death Punch, these bands are as extreme as thrash. How the hell is nu metal higher on the list than this?

Bands include Pantera, Lamb of God, Fear Factory, Five Finger Death Punch, Hellyeah and Down. They're not as heavy as death metal but definitely equal in heaviness to that of thrash metal

Groove metal is also called "Neo-Thrash" sometimes, it's basically slowed down thrash metal with "groovier" riffs

This genre exist! If you don't believe me... Is Thrash Metal with Nu Metal: Slipknot, Disturbed, Drowning Pool, Dope, etc...

I'm pretty sure those are Nu Metal bands that are called Groove. Shouldn't Groove Metal be Pantera?

Way heavier than death or black metal. And Grindcore? That does not deserve to be called music.

Heaviness is about tightness, groove metal is all about tightness and that is why it is the best.

The Contenders

11 Metalcore

Listen to the album "Caliban - Vent" and you will understand why Metalcore is heavier than Black metal and Thrash!

It's not my favorite subgenre, nor do I believe metalcore should be #1. However, due to the fusion of screaming or growling vocals and brutal breakdowns, I stand by that you can find a lot of songs that are heavier than a significant amount of thrash metal songs.

It's a fusion between extreme metal and hardcore punk

Metalcore isn't extreme metal

12 Progressive Death Metal

Cynic is one of the best Progressive Death Metal bands... They do an artistic type of metal, creative too... Because prog is that

Chuck Schuldiner, just saying.
By the way, what in the name of Hell is Power Metal doing here?

Opeth, Cynic, Death... Need I say any more?

Technical, unconventional, death to the 4/4. Still I would remove the "Death" to the name. Bands like Symphony X, Dream Theater, Cloudkicker, Japan X and many more makes this one of the most perfect subgenres of Metal, still a little bit underground but really good.

LOL, these bands aren't prog death metal - they are just prog metal.

13 Brutal Death Metal

How in the WORLD is brutal death metal not at #1.. bands like maggot colony and analepsy make all the other subgenres of metal sound like kids bop...

Brutal Death and its subgenres are superior to any other of genre period.

Easy, number 1 for sure

Why is this not in top 10?

14 Deathgrind

Wow, you haven't listened to Exhumed I think.

Its Death Metal having a mess with Grindcore to produce one hell of a baby. It would probably eat your face off.

Cattle Decapitation. Excuse me, sir, Cattle Decapitation. Would you like some Cattle Decapitation? You want a cup of Cattle? Caffeine or Decap? Cattle Decapitation? Cattle Decapitation? Cattle Decapitation? Cattle Decapitation? Bueller? Bueller? Bueller?

What's this supposed to mean. We get it, cattle decapitation - good band but this is excessive

About as raw and brutal as it gets. bands like exhumed and aborted are ridiculously brutal.

15 Death/doom

My favorite genre. The old Katatonia, My Dying Bride. It fuses the beauty and emotion of doom with death's raw anger which complement each other perfectly.

Autopsy changed my mind about Death/Doom, amazing.

This is the fusion genre of Death Metal and Doom Metal.

16 Funeral Doom Metal

The heaviest and slower genre of metal ever. Pounding drums and distorted bass with brutal growling vocals and depressive melodies make this the most lifeless genre on earth! Mournful Congregation, Tyranny, Thergothon, and Bell Witch are some of the best bands in this genre.

Easily the most crushingly brutal genre

A real underground genre, emerged in the early 90's in Finland. Similar to Death/doom.
Painfully slow, heavily distorted guitars, majestic keyboatrds and extreme deep growls.
Check out bands like Skepticism, Esoteric and Worship.

From a fan of everything extreme from powerviolence to grindcore to slam to blackened death, I can honestly say this is the heaviest genre. Slower than hell, but in a way such as a steam roller would destroy a body. Dark, resonating and extreme to the core. Try rigor sardonicous, mournful congregation, thergothon and evoken.

17 Goregrind

Well if you think last days of humanity and regurgitate are less heavy then cannibal corpse and nile then you are correct. but In reality goregrind while yes can be slow and grindy at times bands like carcass, regurgitate, last days of humanity, rompeprop, etc are in fact much more heavier, but technicality wise death metal is heavier, but if gore grind is below power metal in heavieness this list is wrong. just listen to reek of putrefaction by carcass or putrefaction in progress by last days of humanity for proof that goregrind is in fact much more heavier (not more technical)

Goregrind vocals are clearly the heaviest

This is exactly the same genre like Deathgrind

Last days of humanity

18 Sludge Metal

Definitely the heaviest,craziest metal genre with crazy mind-ill drug addicts as band members,still very talented and expressive.SLUDGE for the win

19 Viking Metal

Svartsot is some really heavy viking metal. Mixes death with folk instruments and viking themes

HOLMGARD AND BEYOND! viking metal is everything one needs.

20 Avant-Garde Metal

Such a variety of different genres in the mix, worth a listen!

Should really be a lot higher than #31.

21 Speed Metal

I like speed metal very much but it's not extreme. Speed metal is just a faster, heavier and more technical version of power metal - some songs by Blind Guardian (Majesty), Helloween (Ride the Sky), and similar.

Some people used to call bands like Iron Maiden and Judas Priest speed metal in 70s and 80s.

22 Technical Thrash Metal

A relatively small but awesome subgenre - it's sophisticated thrash. Some of the bands are Annihilator, Coroner, Vektor. One of my most favorite metal subgenres.

23 Stoner Metal

It's not extreme - there's nothing extreme here. Not fast and not aggressive. And vocals are clean.

24 Slamming Brutal Death Metal

I mean if this list is all about extreme then yea this is about as extreme as it gets

This is on par with Brutal Death, I feel they should have been put on the same listing.

This is the most hardcore, fast and heavy genre of music ever. The vocals are so brutal that you can't even understand them. The drums are like thunders and the guitars are so distorted that you can't even distinguish notes. Just listen to Devourment and you'll understand what I'm talking about.

Nothing has as crushing of a sound as this, but according to this list, power metal is heavier.

25 Nu Metal

Nah. I'm gonna pretend I didn't see this.

Don't confuse it with hip-hop, electronic rock or electronica. This is technically Metal with Hip-Hop

Um, what? Nu-"metal" isn't even metal at all, and not even CLOSE to extreme metal. Its influenced by hip-hop more than anything.

Awesome turntables and synthesizers. A creative sound. And this is not alternative metal for those who can't categorize right. I like bands such as Slipknot, System Of A Down, and Disturbed.
