Sunn O))) - Black One

I'm not even going to try to explain this one since this does it perfectly:

"For the last decade, the duo of Stephen O'Malley and Greg Anderson have been taking the doom side of heavy metal so far from those three legendary chords from Black Sabbath's immortal "Black Sabbath", it feels like a completely separate dimension, as if you expect to slip into a black hole for eternity. The blackest of the black, the bleakest of the bleak, Sunn O))) combine high art with brutal power like no other, composing music that dares listeners to sit through it all, locking them into sludgy grooves so slow, so hypnotic, it will either have them repulsed, enthralled, or better yet, both. It's easy to shrug off Sunn O))) as nothing but pure, arbitrary noise, but the more you delve into their work, the more you begin to sense a structure to the music that's as lethargic as it is dreary. It's mood music for the worst of moods.

Like the voice of the undead, it's pure cinema, a blend of shock rock, black metal, and ambient music, and the overall effect is devastating."
