Repulsion – Horrified, these guys influenced everyone: Death, Carcass, Napalm Death, Autopsy, etc.
Order from Chaos - An Ending in Fire, intelligent, raw and unique USBM
Blood - Depraved Goddess, these guys are the only first wave grindcore band I know of that still plays old school grindcore. This album is their best.
Hate Forest – Battle FielRAB, this is easily the best European black metal release of the decade
Vomitor – Bleeding the Priest, the best Australian black metal
Slayer – Hell Awaits, duh
Vio-Lence – Eternal Nightmare, did you heard? Robb Flynn didn't suck at a time.
Godflesh – Streetcleaner, way ahead of its time
Blasphemy – Live Ritual – Friday the 13th, fantastic band whose songs were often raped by horrid production
