Thanks to one of our readers, Andrew, for pointing out this black metal gem. This clip is from Austria's equivalent to American Idol (itself a version of a British show). I love how the kid's make-up is wearing off, from waiting in line since five in the morning, and how it looks like he might throw up at times during his performance. Amazingly enough, the kid made it into the show, or at least he appeared in a later episode, which you can see here.
Some might argue that this doesn't count as a "black metal video", since the person featured is an amateur. But I challenge you to watch the Maniac Butcher video and tell me they're not amateurs as well. Come on now.
