For this week's #PrivateJam, DJ Spooky—the man who exemplifies the idea of the disc jockey as artist and creator of new music—cited Prince's epic seven-minute jam "Controversy" as the song he'd be "really embarrassed to be caught doing air guitar to." He says, "I remember when Purple Rain and stuff like that came through. I always felt it was reaalllly slick and pop. When I was a kid, I liked more independent and underground music like Fugazi or Minor Threat and Bad Brains, and didn't like pop that much. But there's something about Prince…" There's no better guitar legend to air guitar to, we'd say.
