diSEMBOWELMENT - death/doom pioneers
Corpse Molestation/Bestial Warlust for black metal of the savage and primitive side
Hobbs Angel of Death - classic thrash metal
Abyssic Hate - Burzumic black metal
Vomitor - nasty black/thrash metal (Australian metal is rife with this kind of music)
Elysian Blaze - funeral doom
Mournful Congregation - also funeral doom, among the best in their genre
Midnight Odyssey - recently acclaimed black metal/ambient act.
Myrddraal - Wheel of Time-themed black metal
Paramaecium - also early death/doom pioneers, this one Christian-themed.
Mortification - actually kind of a crappy band, what little I heard of them, but they share a member from Paramaecium and also are Christian-themed metal (death metal to be exact). Early albums are supposed to be OK but haven't heard them.
Sacriphyx - OK band, some here might like them, war-themed death metal with a hint of classic heavy metal influence.
The Berzerker - some blastbeat-heavy industrial/death metal kind of group I haven't heard but were a big deal at one point.
Striborg - one-man lo-fi wintry/foresty black metal with lots of Norway worship. Have like a million releases.
