Some Norwegian dude who just happens to be one of the best musical geniuses ever. His band, Burzum, totally defines black metal. The later works of Burzum are ambient, but the earlier stuff was black metal, usually with excellent use of keyboards. While his music may be great, I tend to disagree with his beliefs when it comes to politics.
Varg Vikernes is the frontman of a black metal band called Burzum.
