Exmortes are like, amazing. Trance-induced, trance-inducing repetitive black metal from late 1980's Netherlands, brought to you by one person, Verpus. Of the two EP's I heard, Hear The Saw has less loud vocals and more flange, and Fuckin Nightmare (1989) has louder vokills and more buzz-saw gtr aktions.
I include also Fuckin' Nightmare because yeah. Exmortes totally rules.
