Check out Wolfmangler and Dead Raven Choir, if you don't know them already. Both are projects of D Smolken, a Polish-American musician.

Death metal played on acoustic instruments would be one description, but that would ignore the sparseness and dramatic use of silence in his music. Very much something you'll either love or hate. Me, I can't get past his Bela Lugosi goth vocals, but I like the music very much indeed.
