You got it, serious EXTREME fucking metal, be it funeral doom, brutal death or whatever. Songs so well composed that could make a real fan of music realize that he can enjoy that genre.
The ones I can remember right now:

Nile - Execration Text

Cephalic Carnage - Endless Cycle of Violence

Cryptopsy - Phobophile

Krisiun - Apocalyptic Victory

Suffocation - Thrones of Blood, Infecting the Crypts, Pierced From Within, Suspended in Tribulation, Human Waste, Bind Torture Kill, Blood Oath, Marital Decimation, Effigy of the Forgotten ( i could go on forever but I'll stop here)

more to come in time, just don't feel like going through everything at the moment.

EDIT: MOAR IS HERE

Bolt Thrower - World Eater/Cenotaph/The Killchain

Darkthrone - Transilvanian Hunger

Behemoth - Conquer All

At the Gates - Blinded By Fear

Unhallowed/Funeral Thirst - The Black Dahlia Murder

Spheres of Madness, Day 69, Winds of Creation - Decapitated

Mount North, One by One - Immortal

Freezing Moon - Mayhem

New Millenium Cyanide Christ, I, Bleed,etc - Meshuggah

Lashed to the Slave Stick, The Eye of Ra - Nile

etc

i went to see suffocation live on november 15th and it was the most dominatingly heavy death metal i have ever seen performed live. i didn't think "bind torture kill" could be any heavier until i experienced it up close.

That's why they're the best.

Mercyful Fate - Satan's Call

anything by Cryptopsy besides new album is definite win, Flo is the best drummer I've seen ever.

Is Pig Destroyer allowed in this thread? Cuz most anything by Pig Destroyer (Natasha!)

Fucking Soilent Green -- Antioxidant

yes

Pig Destroyer - Towering Flesh

Good choice.

I'd chose Piss Angel and Natasha for mine by PD.

Also; Kafir, Iskander Dhul Karnon, Annihilation of The Wicked, and Lashed To The Slave Stick by Nile, and Slaves Shall Serve by Behemoth, At the Gate's cover of Captor Of Sin.

Good topic
For me right now, it is FUCKING PORTAL. These motherfucker's are from a fucking different dimension or something. Wershipper from the new album Swarth is one of my favorites.

PORTAL - Glumurphonel

The new Agoraphobic Nosebleed album will def be a top 5 album for me at the end of the year. I also love Pig Destroyer but I think Agorapocalypse trumps all PD.

I need an Agoraphobic Nosebleed tour dammit.

Fucking Bolt Thrower - World Eater man.

is Stapping Young Lad extreme enough?

i would definately call relentless an extreme metal song

LOL WHAT THE FUCK, MAN

That was the only reply that actually made me curious to check out the mentioned song, and that was fucking OUTWORLDLY!

How come i never heard of those guys?

I have no idea, Portal are kind of the rising stars of the underground metal scene lately. I keep seeing they stuff everywhere. I'm gettin' to see them at MDF this year

Ive always been partial to More than words by Extreme.

warface are an awesome death metal band. laura chrisitne is a brutal shredder.

OUTWORLDLY, now that is a word that does these guys justice. Just check out the Swarth album. It's an acquired taste but since you came up with an extreme metal thread it could possibly right up your alley. Blaze up, drink up or whatever it is you like to do and turn that shit up. The term brutal will have too officially be redefined.

Indeed. I love how it's so groovy.
