I just wanted to see if anyone can reccomend some good "heavy" (rock, metal, sludge, stoner, doom or whatever) bands that most people have probably not heard.
Not bands like Korn, Limp Biscuit, Slipknot or whatever is on MTV everyday.

I'll start with a few

Eyehategod
Electric Wizard
Acid King
Neurosis
Buzzov•en
Bongzilla
Fu Manchu
Sleep
Unsane

Queens of the Stone Age
Hella
And You Will Know Us By the Trail of Dead

.... in which case I guess we should consider Kyuss and the occasional band of their sometime producer, Chris Goss, Masters of Reality.

I just saw the A Life Once Lost/The Red Chord/Caliban tour, and all three of those bands were awesome. You can check out The Red Chord and A Life Once Lost mp3s here

Other bands:
Isis
Old Man Gloom
An Albatross
Botch
Cave-In
This Day Forward (older)
Pg. 99

SKEPTICISM

the masters of funeral doom. Beginners should check out Lead and Aether or the EP Ethere, but stay far away from the new EP The Process of Farmakon.

Other great doom acts to check out are Morgion and Evoken.

All out War

Buried Alive

Earth Crisis

Rigor Mortis

Strangely enough, all of the above mentioned bands have broken up.... but they still rock.
