Outdoor electronic festivals can be real time-warps. They’re often every bit as stylistically divergent as an old mega-rave, with an emphasis on now-retro big-room big names. The Electric Zoo doesn’t entirely abandon that template. Its four stages host venerable titans including crossover superstar Moby; New York house legends Victor Calderone and Danny Tenaglia; Euro populists Tiesto, Armin van Buuren, Carl Cox and John Digweed; and Detroit/Windsor techno pioneers Carl Craig and Richie Hawtin (under both his birthname and his Plastikman guise). But there are some happy surprises to this bill: Fool’s Gold’s Nick Catchdubs, M.I.A.-collaborating reformed bro-stepper Rusko, left coast leftfielder Daedelus, Poker Flat/Dessous housey minimalist Steve Bug, beatboxing Beardyman, Mehdi and Riton’s Chicago-focused side-project Carte Blanche, Kid Cudi-remixers Crookers, Kompakt’s Gui Borrato, dance-poppists Chromeo, multimedia geeks Super Mash Brothers, and global bass curator Diplo are among the more than 100 artists making appearances.
