I fucking love this album. It's such a cool, unique album even though on paper it sounds like it shouldn't work at all. Black metal with banjos and flutes? Random protest song interludes? Samples of some grizzled old coal miner talking about being beaten by the foreman and going on strike? What the shit? But somehow it works, for me anyway.
The couple of albums that came after this are a little more traditional black metal and not as heavy on the bluegrass stuff, but still really cool. Dude is involved in like six other bands too. He's prolific as hell.
