Musically, Skrillex's incessant bass wobbling dominated the set. It never stopped; it was only modified and tweaked. He was a showman, encouraging the crowd to get loud in a surprisingly shrill tone. The interesting thing about a Skrillex set that makes it worth experiencing once is its complete package: the surreal, purposely trippy video clips (anime, a stomach-churning "Thriller" knockoff, "The Fresh Prince of Bel Air" theme) are nightmare-inducing, the laser show looked expensive and there was that wobble, like constant banging on a door. It's disorienting.
