Hats off to Concord for recognizing that teenagers are a major fanbase for EDM-and that some of us are too old to rage until 2am. Hence the 5:30pm show. While the rest of the boys were duking it out on the playground, 31-year-old Gartner, a.k.a. Joey Youngman, was firing up the drum machine. Since then, he's produced dozens of tracks for Ministry of Sound, Toolroom and Ultra. His jacking melodic techno is the main attraction here. Currently a member of the hipster electro elite, Aussie Tommy Trash got his start as a rocker before the dance floor won him over. Now he's releasing grungy dance remixes for mau5trap, Dim Mak, Subliminal and Toolroom.
