Slayed Necros
Void
Eventually I ended up liking Eucharist even more that you do, seeing how they're absent from your list
And I remember mentioning Creepmime along with other Finnish OSDM bands, but apparently they're Dutch. The Greys wasn't way off then when he said they reminded him of Pestilence.
I still need to check out Gorement, Argentum and Depravity
Argentum isn't strictly old-school death metal. Ad Interitum Funebrarum is one of the most diverse metal albums I've listened to, with influences from doom, black and death metal, and masses of non-cheesy symphonics. It's one hell of an album.
