I usually hate keyboard-laden extreme metal, but Tribe is an awesome album despite sounding like Atheist playing Castlevania songs. Still haven't gotten around to buying Crust or their last two albums, although I really ought to. I have to confess that I'm not too huge on the debut though, which has some good riffs here and there but overall sounds too primitive for a death metal band not based in ferocity.
Tribe, Crust and s/t are very good. Above the Light is one of the best progressive death albums I have ever heard, and a rather underrated album. Their other albums are not worth giving a damn about.
