Best Anachronism: Jack Ü
As abused as the term "trendsetter" is, the Jack Ü dudes are nothing if not that – forward-thinking producers bringing the hyperactive sounds of modern rave (that's Skrillex) and an arsenal of international body music (Diplo) to the pop charts. These are the guys who made the Biebs relevant, after all. And while Justin didn't appear, other of-the-moment vocalists did, like AlunaGeorge, Kiesza and Post Malone, while the dÜo blasted out their throbbing cacophony of warped horns, pitched up voices, hi-hat clatter, laser zaps, bass and big hooks. However, Jack Ü's future-crunk battle-station was perched atop a gigantic replica of a boxy Apple II computer, complete with a floppy disc that, at one point, proved itself big enough to cover Diplo's entire body. ROYGBIV graphics and grayscale games played across the bulbous screen – one subbed in umlauts for asteroids while another sent the Ü snaking through a Wolfenstein-like maze – with breaks for the ancient operating system to call up jiggling images of pointillist palm trees and sadly rendered spheres. The only modern prop was Kanye West, who stood in front of the console and nodded his head during a remix of his 2010 cut, "Power."
