41. R.U. Dead? - Promotape 
Okay, I know the band name is ridiculous, but just trust me on this one. This was a full-length demo and never saw a proper release, but it's one of the most astounding slabs of death metal I've ever heard. The band was formed by Uli Hildenbrand after the dissolution of Poison and continued largely along the same track, with a more refined sound that seamlessly merged Teutonic thrash with Autopsy-style doomy death, while also blazing a trail with sprawling compositions and classy guitar interplay. In a lot of ways, this band laid the blueprint for bands like The Chasm and Dissection. A true classic lost to time.
