This video is awesome an hilarious.  Somehow, a rogue viking, while trying to find Danzig, accidentally got stuck in a Crystal Castles crowd and wielded his battle axe in frustration and in defiance of electrosmash.  What you didnt see here was...

 ...heads flying everywhere as he began to lop off domes to make his way to the black stage. It looked like popcorn popping.  But with heads.  It was really scary. We still have not found this man.  And we still do not condone the hand gestures with glow sticks at the beginning.  It just makes you a target.
