Thanks!pestilence-testimony of the ancients & spheres
brutality - screams of anguish
gorguts - all
cynic - focus
atheist - all
nocturnus - the key & thresholds
demilich - nespithe (crappy vocals..)
sadist - tribe & above the light
assuming that you've listened to death,morbid angel,immolation etc...start with these...you'll really wont need smth else..
However, I wouldn't agree that Demilich has crappy vocals. I think they are really unique and interesting.
