Top 10 Best 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

Death has to be the most extreme. I've never heard a Thrash Metal song about ripping entrails out of a virgin or a song about ripping flesh off of someone's body and wearing it as a mask. Even Slayer and Kreator don't sing about stuff like Cannibal Corpse, Six Feet Under, or Morbid Angel. So Death is the most extreme!

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 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.

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... read more

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.

Thrash is most extreme and it sound heaviest and just Thrash! Thrash Metal was push to all other extreme subgenres of metal. Genres like Death, Black and Groove Metal, and also Grindcore and Deathcore. Thrash is extreme life

3 Black Metal

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.

Death, Black, Death-Doom, and Funeral Doom are pretty much the only metal sub-genres I find myself gravitating to the most. I don't dislike other sub-genres, but they no longer captivate me as much as they did during the initial phase. Once you immerse yourself into or embrace extreme metal, the lust for dark music only intensifies after each listens.

4 Melodic Death Metal

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.

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

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

5 Doom 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.

6 Grindcore

This is where we reach the end of music. This is the most noisy genre that can still be considered music before you start entering real noise territory. I'm not sure why this isn't #1 though. It combines the extremes of goregrind and harsh noise, and offers loud guitars, fast drums, and outrageous vocals.

Grindcore might not have the most disgusting lyrics, such as stuff, listed in the death metal description. Yeah, of course, some bands like AnalC*nt can go far and sing about pornogring or gorerind, I forgot, but I'm talking bout those bands, who actually formed grindcore as a genre. For example, my favorite band Napalm Death. They are the fathers of grind and no one can deny that, but if you take a look at lyrics, or try to actually listen to em, you wont hear them singing about a woman, whose eye got poked out, and then someone with aids, no-no-no. They are singing about politics and about not bring treated fairly. The true heaviness comes with the music. Listen to their first album, "Scum" its called. Only the drums will make your ears bleed badly within the first minute of any song, lets say "Instinct of Survival". If you listen to their last album, "apex predator - easy meat", maan, not only your ears will bleed, but your teeth will brake and your brain will run away. After all, to conclude, I wanna say: death metal is damn heavy, but half of this heaviness is reached within the lyrics, grindcore is heavy because of its music. Yeah, that it, haha

7 Blackened Death Metal

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.

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

8 Technical Death Metal

Off of topic if Progressive/Technical... Technical Death and their branches is one of the most important variations in the last decade in metal, the techsdeath musicians have skills beyond than the thrashers, the aggressiveness are equally to any black, and the fussion/progressive songwirting it's at the same level of other bands dedicated to his genre; it's not a war about definition it's about recognize one of the genres must underrated/polemic in Metal! this goes from Obscura to Quo Vadis, from Origin to Nile even Gojira licks this genre. Thrash Forever! but Techdeaths are in my heart!

9 Deathcore

It's brutal and unforgiving to both the listener and performer. Whether or not you like it, I would argue that it is heaviest by the fact that it can incorporate all the intensity of death and mix in the rebellion that hardcore punk was founded on.

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.

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

10 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.

Brutal Death Metal is strictly heavier than Death Metal hense the name. How is Death Metal #1 and this 11?

The Contenders
11 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)

12 Funeral Doom

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.

Genres like Sludge, Death - Doom, Grindcore, and Tech Death can be extreme at times, but the genres most consistently falling into very extreme music are Funeral Doom, Slam Death, DSBM, and Goregrind in my opinion.

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.

13 Viking Metal

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

14 Sludge Metal
15 Metalcore

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.

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

Metalcore is a good genre. It actually has melodies and can be artistically creative. Haters gonna hate, it's good if you're openminded and aren't a bandwagoner which is what metal should be all about anyways.

16 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.

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

Autopsy changed my mind about Death/Doom, amazing.

17 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.

18 Depressive Suicidal Black Metal

Amazing, bands like Silencer are the creepiest thing I've ever heard. It should get more votes.

19 Stoner Metal

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

20 Slam Death Metal
21 Pornogrind
22 Crossover Thrash
23 Mathcore

Even brutaller than technical death metal because of the lack of melody and more noise, and grindcore because it's technical.

And why the hell is power metal in the top ten? Idiots.

24 Progressive Death Metal
25 Blackened Deathcore
