Heaviest Metal Subgenres

I may REALLY hate death metal but I agree its heavy.
There's only 2 bands of this subgenre: opeth and death but I respect anyones opinio
Black is close but death just swerves in front!
Brutal death metal is Death metal!
Brutal death metal!

While I don't listen to it that much, I do have to say that it is very heavy. Some of the experimental stuff borders on just being noise. If you want some of that stuff, listen to Torture and Havohej.
Some of its really heavy. Immortal, Marduk, gorgoroth, 1349, and emperor are probably the heaviest. Others like mayhem and bathory are about as heavy as a thrash band
Thrash metal is heavy. In one way its heavier than Black metal but ultimately black metal sounds heavier cause it's a lot faster than thrash metal.
Swedish black metal is more violent than brutal death metal.
Bestial black metal is the brutal death metal of black metal

Thrash is definitely heavier than black metal. Master of Puppets ain’t that thrashy. Try their first two albums and another old school Thrash bands, especially Slayer. Then you will find the answer.
Thrash varies in heaviness. The heaviest thrash bands are probably:
Kreator
Possessed
Slayer
Skeletonwitch
Sepulutura
Sodom
Repugnant
Ghoul
Exodus
Havok
Toxic Holocaust
Iron Reagan
Metallica,Megadeth And many Anthrax are not too heavy but I don't like thrash I am into hardcore punk
fast, heavy, hard... what's not to love?

Since it mixes hardcore and death metal, you get the best of both worlds. You can hear the aggressiveness of hardcore and the sheer heaviness of death metal. There are plenty of breakdowns in this genre, so if that's up your alley, go listen to bands like Suicide Silence.
Fused with Black Metal (blackened deathcore) this is unstoppable
Shrine of Malice,
Signs of Swarm,
Lorna Shore,
A Night in Texas..
When it comes to music that avtually tries to mentally cut its listener with a razer then thrash, death/thrash and grindcore win. But when it comes to heaviness as in "the music that makes you feel like you're trying to lift something heavy," deathcore, funeral doom and death doom win, no brainer.
Deathcore fuses the traditional death metal styke with growls and metalcore screams along with typical "core" genre sounds and breakdowns and pig squeels which makes is the heaviest genre relying to music,if we talk about what the song talks about the heaviest out there is black-blackened death metal, but as to the music...DEATHCORE

Big fan of speed metal but this is too heavy for me
Stupidly heavy for a kind of music
Heavier than thrash
Slow, heavy, amazing

Userguy44, Grindcore is the combination of Death Metal and Punk. That makes it Metal. It also usually leans more to the Death Metal side. It's rare as hell to see a band that leans more to the punk side.
There is a point after which it is funny instead of heavy
Grindcore isn't metal.
Napalm Death
Carcass
Aborted
Pig Destroyer
Agoraphobic Nosebleed
Extreme Noise Terror
Repulsion
Terrorizer
Nasum
Brutal Truth
Blackened death metal fuses the death style with satan and anti-christ speaking text. This top is really crazy because thrash metal is too light compared to this or other metal subgenres which contain screams,growls and pig squeels with fast rhythm and heavier guitars,people only know metallica and other famous bands and they do not know what they are voting for
the 2nd heaviest metal subgenre, only loses to slam
Cannibal corpse!
Technical Death Metal has 2 sub-groups:
1) Brutal Technical Death Metal: this is really heavy (Cryptopsy, Gorguts, Nile). Technical Death Metal is on this list mostly for this sub-group and should be higher. It's much heavier than death metal and thrash.
2) ordinary Technical Death Metal: it's less heavy than the 1st group and is more melodic (Necrophagist, Obscura, Quo Vadis)
Technical Death Metal's heavy but I can listen to it more comfortably than death metal. Maybe because its technical.
Go Listen To Gojira there the best Technical D Metal band out there
Fast, technical, heavy
Slower thrash, need I say more?
Sepultura
Lamb of God
Pantera
slow thrash, with more headbanging
Take a listen to Pantera,Machine Head,Gojira and Sepultura
Come on whats more heavier than this genre, look at the title, it even sounds heavy, the songs tend to have insanely fast tempos, very heavy sounding riffs, lots of double bass drum, and the vocals are so damn brutal that you can't even understand them.
by far the heaviest sounds a human can produce
My fave bands are Nile and Cryptopsy
Slam is a genre that is based on two things in its most basic form: extremely guttural vocals, and lots of chug riffs. It is generally agreed upon that it started when people listened to the album "Effigy of the Forgotten" by Suffocation. There was specifically this one riff in the song "Liege of Inveracity" that really defined the sound of the genre. The timestamp for that riff is at 2:51 if you were wondering. Some bands I recommend are Epicardiectomy, Cerebral Incubation, and Devourment. I think that Devourment is probably the most entry level band out of these three, so give them a shot, but don't think it's going to be baby stuff either. If you want even more info about the genre itself, watch the Punk Rock MBA's video called "What killed Slam?"
Go listen to Gutted Face.
Slam is a genre. It's a type of BDM that focuses on the heaviness snd atmosphere of weight than BDM, like Cannibal Corpse. Usually, the vocalist is a frog, and the song is mainly slams (similar to djents, but far less syncopated and done by the guitar, bass and drums)
Some slam bands you should check out are: Extermination Dismemberment, Visceral Disgorge, Devourment, Gutteral Slug, Abominable Putridity, Malodorous, and Pathology
Good luck with the whiplash
Heaviest genre, no question. Just not for every metal fan oout there.
heaviest. end of discussion.
Extreme Metal is an umbrella term that covers thrash, Death, black, grind, and doom Metal. So this list doesn't make sense
Extreme metal means heavy genres of metal. It isn't a sub-genre.
Extreme metal is heaviest metal!
Extreme Metal is not a genre.
Prog metal never seemed heavy to me.
There’s so many different kinds that there’s bound to be something really heavy in there
There's nothing heavier than the sound of eternal darkness and suffering that feels like a cold wind blasting on your face during the cold blizzard of the nuclear winter. You could as well eat raw flesh and sacrifice your own eyes to the Satan and scream in agony while blood drips all over your face from your eye sockets while listening to Drone Metal.
heavy, and goes on forever
Yes, speed metal is quite heavy.
Is horror Metal a thing?
What is horror metal?
No such subgenre (another example of people making a genre name based on lyrical themes and not on music)
Not that heavy but needs to be higher. It got Slipknot, Soulfly and (referring to old school now) Linkin Park.
As much as I love Nu Metal, this genre has to be the least heaviest subgenre.
Hated or not, stuff like early Korn is undoubtably heavy.
Ha ha! Is this a joke?

Just because heavy metal has a name "heavy" doesn't mean it's the heaviest metal genre. Rather I'd choose heavy metal as a soft metal genre. Heavy metal is very soft comparing to Black, Death or Thrash metal.
This genre defined what Heavy is.
And it got Heavy in its name
