Building off the pas-de-deux pastiche of Daft Punk, Skrillex once and for all made it permissible for DJs to do virtually nothing technical, or even musical, onstage – that is, if they provided something else interesting to watch. In the past, that included wearing a helmet or a mask, but for Skrillex, it meant bouncing behind the decks like a jumping bean in a slam pit, pumping his fists, raising his arms, and hooting into a mic. His shtick was so kinetic for an electronic-music performer that he earned a rep for being "great live," simply due to the energy in the room. His extremely young, blindly agog crowds were certainly startling to witness.
