Community star, stand-up comedian and rapper Donald Glover came by the Rolling Stone studio recently to perform a handful of songs from Camp, his first album as Childish Gambino. "I think the only reason I'm allowed to do this is that rap isn't that serious anymore," Glover said after the set. "Hip-hop started in a fun, silly place, and I don't think I need to tell people it's a serious thing. It's fun!"
