Stereogum writer Tom Breihan saw a Skrillex show at SXSW and loved it. In fact, it was his favorite act. His takeaway was that the Skrillex many people deride as a one-trick WUB WUB WUB pony on the basis of his albums is an extremely effective and talented live DJ.
But what I found was one of the more dynamic sets I heard during all of SXSW. Skrillex, see, knows what he's doing. He does what great DJs do: He layers sounds and ideas on top of each other, building tension and releasing it, moving fluidly from one thing to the next. Parts sounded like the sort of early-'90s hardcore techno that was popular with people who wore lots and lots of smiley faces. Other parts sounded like the sort of dark, broody late-'90s breakbeat techno that was popular with scary white guys with dreads. There was also a lot of robotic one-drop reggae in there. Early on, Skrillex played a big chunk of Damian Marley's "Welcome To Jamrock" unmolested. Later, he dug out Ini Kamoze's "World-A-Music," the song that Marley sampled on "Jamrock." All of it fit in seamlessly. None of it was built around bass-drops.
