Black Metal.
Dead Raven choir turns up the distortion on his bass guitar to mammoth buzzing heights, bows his bass fiddle, and snarls and screams songs by Leonard Cohen, Townes Van Zandt, traditional European and American folk, and the German poet Rainer Maria Rilke. The music mostly drifts along at a slow, rolling pace, with the wash of distortion smearing into a serene sound scape, and the bass fiddle, which sounds like a cello to me, leads most of the melody. The vocals are way back and drift in and out, completely raspy and shredded. I'm pretty sure many of the vocals are in another language which just adds to the mood. Some songs have the low din of drone scape underlying the music too. While most of the music is harsh, eerie, cold and abrasive, much of it is still somehow quite peaceful.
