The Summer of Chance
If you're going to a major festival, expect to see Chance the Rapper. After the massive success of last year's Coloring Book, he's headlining four major fests including Bonnaroo, Lollapalooza and Firefly – about the same number of festivals Outkast played for their big reunion in 2014. "It's safe to book Chance everywhere," says Adam Voith, the agent for Mumford & Sons and Bon Iver. "He's on top of the world."
