Top Ten Death Metal Subgenres

This is the most accessible Death Metal subgenre and may open the door to other Death Metal subgenres. Amon Amarth was the band that made me a death metal fan because they helped me overcome the barrier of the death growls.
Children of Bodom are great. Also Arch Enemy, Insomnium, and more.

First melodic death metal songs I liked were In Flames songs but the band that made me fan of melodic death metal was Amon Amarth. Then I came interested in other great bands as Arch Enemy and Scar Symmetry.

Melodic and tech/prog are my two favorites

Mixture of Brutality with Beauty. (i.E. death Metal with Melody)

Currently it's the #1 metal subgenre for me - some of my fave metal bands are namely from this subgenre: Nile, Obscura, Cryptopsy, Brain Drill, Gorguts, Necrophagist, Beyond Creation, and more.
If you wanna hear some exceptional musicianship (insane drumming, a lot of sweep picking, fretless bass playing, etc), this is the right subgenre to check out. But I have to admit it's one of the heaviest and most complex Death Metal subgenres so it isn't easily accessible.

Technical death metal is absolutely amazing. It makes an already amazing genre so much better. With bands like Death, Fleshgod Apocalypse, Beyond Creation, Necrophagist, Archespire, Nile, Suffocation, Dying Fetus, Spawn of Possession, Decapitated, Origin, and Obscura, technical death metal is by far the best death metal subgenre.

Insane subgenre! Hour of Penance and Origin are the first two that come to mind.

This is the classic mixing of Death Metal, Progressive Rock & Jazz.

This and death doom deserve to be higher!

The best death metal is the oldschool as every metal, oldschool is the best

Although I prefer technical death metal, I’m voting for this because it deserves to #2. Also OSTDM is absolutely amazing.

Death, Morbid Angel, Possessed, Deicide, Cannibal Corpse, Obituary, Jungle Rot, Six Feet Under, Gorguts, Hate Eternal, Massacre, Vital Remains

Opeth, Edge of Sanity, Gorod, Akercocke, Atheist, Pestilence, The Faceless, Obscura, Martyr, Sadist

Reason why death metal is still alive.

Dying Fetus, Nile, Suffocation, Abominable Putridity, Devourment, Brain Drill, Origin, Benighted, Pathology, Kraaniun, Putrid Pile

This is too low... I prefer OSDM and death n roll but this needs to be higher!

Fusion genre of Black Metal & Death Metal.

Behemoth, Goatwhore, Acheron, Angelcorpse, Blasphemy, Nunslaughter, Belphegor, Akercocke, Necrophobic, Tartarus

Fusion genre of Death Metal & Doom Metal.

Autopsy, Incantation, Disembowelment, Katatonia, Saturn's, My Dying Bride, Paradise Lost

Nile and Suffocation would fall under this category (Brutal-Tech), Atheist and Gorguts are Fusion-Tech while Cynic and Death are Prog-Tech.

Brutal vocals, sweep picking and blast beats galore.

Nile and Cryptopsy!

Entombed was the creator of this genre. This is a typical Death Metal sound with Garage Rock (Rock n Roll) elements.

Entombed, Six Feet Under (Graveyard Classics)

This one is not a specific subgenre of Death Metal, but bands like Nightfall, Septic Flesh etc. Created this genre by mixing symphony materials into Death Metal.

This is not a particular genre, but some bands like Nightfall, Septic Flesh etc. Combined symphonic elements with Death Metal and this subgenre was created.

Codex Omega by Septicflesh is awesome.
Fleshgod Apocalypse are great, too.
Mayan are good as well

Septicflesh, Fleshgod Apocalypse

Abominable Putridity, Pathology, Putrid Pile, Cephalotripsy, Katalepsy, Kraaniun, Vomit Remnants, Vulvectomy, Acranius, Ingested

The quick intensity of thrash combined with the brutality and darkness of death metal

Ghoul, Revocation, Repugnant, Possessed, Legion of the Damned, Pestilence, Battlecross

Vader, Legion Of The Damned, Torture Squad!

Bands include Naglfar and Dissection.
Dark, brutal and melodic!

Dark, brutal, melodic and powerful.

Not a music genre - just group of Death Metal bands who use Christian lyrics

Immortal Souls and Becoming the Archetype are worth checking out.

Basically it's early Fear Factory

This isn't a music subgenre - it's goregrind/grindcore with specific lyrics. Not even sure these bands are metal.
