2009 summer music preview

Hottest DJ: A-Trak

After making a name for himself as Kanye West’s touring DJ, this Canadian wunderkind (who won the prestigious DMC/Mixmag World DJ Championships when he was just 15) finally seems poised to become a breakout star on his own. He’s got two hotly tipped mix CDs making the rounds, “Fabriclive 45” and “Infinity +1,” both showing off his funky, breakneck mix of hip-hop, electro, house and mashups—and he's rocking a prime spot on the Bacardi B-Live tour alongside a who’s who of hipster approved acts (Santigold, Diplo and Switch, Matt and Kim, MSTRKRFT).

Other hot DJs: Claude VonStroke, Boys Noize, Nic Fanciulli, the Glitch Mob.
