82. Necro Schizma - Erupted Evil demo - (1989)
Imagine if Hellhammer had recorded an entire demo of those slow, doomy songs like "Satanic Rites" that they would explore with more skill in Celtic Frost. That's pretty much what Necro Schizma did. Ultra-heavy and primitive, but without being droney, these dudes are the sound of first-wave black metal played at a snail's pace, with the brutality updated to be on par with late-eighties death metal. Quite possibly the first true death/doom band, and one of the few to never play with any speed even approaching mid-pace.
Another thing I love about these guys is that their abrasive, lo-fi production gives their music the evil atmospheric vibe of black metal. However, unlike black metal, the slow pace of the songs allows for that atmosphere to really descend into the spaces between notes like the fetid stench of the grave. This is a truly fugly, low-rent recording, only to be listened to by those who love death/doom with a passion. I'd say too bad they never released an actual album, but I doubt they could have built on this sound without ruining it to some extent.
