Slayed Necros
Void
Electrocution - Inside The Unreal (great old school thrashy death, on par with the likes of Pestilence, Asphyx, etc.)
Morpheus Decends - Ritual of Infinity (as good as the debuts of the "big" NYDM bands)
Disaffected - Vast (atmospheric doom death metal. as good as the CD is, one would think it would be widely praised)
Necrophiliac - Chaopula: Citadel of Mirrors (very good old school death metal in the vein of Incantation. even good for old school death metal, yet unrecognized)
I'll second all of these, although I can entirely understand why none of them are universally praised, even by Old School Death Metal fans.
Seance - Saltrubbed Eyes.
Most prefer the chaotic debut, but I feel Seance truly shines on their sophomore effort. While the debut was essentially a fine mixture of the Stockholm and New York styles, Saltrubbed Eyes saw the band refine this style and create something completely fresh and unique. Essential Swedish Death Metal.
