Frank Ocean performed at Los Angeles' The Wiltern last night for his Channel Orange release show, and the night offered up a few nice surprises. For those lucky enough to have been there, Ocean was joined on stage by fellow Odd Future member Earl Sweatshirt for the song "Super Rich Kids", and the attendees couldn't help but scream wildly as Earl strolled in casually. The screaming didn't stop there, either, as Ocean's cover of Prince's "When You Were Mine" got a huge reaction from the crowd. Check out fan footage of both after the jump.
