I know "Transilvanian Hunger" has been said, but what a beautifully complete album. I still haven't found another bm album as consistent as TH.
Cryptopsy - None So Vile
Napalm Death - Scum
Massacra - The Final Holocaust (But I prefer the raw aggression of '88 demo version as opposed to the polished official release, though it's excellent)
At the Gates - Gardens of Grief
Kayo Dot - Choirs of the Eye (kinda pretentious, I know)
Though it was "Ride the Lightning" and "Master of Puppets" that initially got me into metal, there are definitely skippable tracks on both. For the first time in years, I listened to all of "In the Nightside Eclipse", and I can't really remember why I used to enjoy it so much. It just sounds ineffectual to me now as a whole.
