I'm a huge fan of Skrillex (my signature is a bit of a dead giveaway, haha).
Saw him live in Seattle back in January, definitely one of the best shows I've ever been to.
Excellent stage presence, and he knew how to keep a crowd under control during technical difficulties.
(The bass randomly died in the middle of his set, and it was a good 5 minutes or so before they were able to bring it back up. XD)
