Last Thursday, vitaminwater and FADER kicked off 2012's uncapped concert series in LA with surprise performances from Rick Ross, The-Dream and Zola Jesus. Unexpected guest Omarion, a new, Cali-based MMG signee, popped up during Ross' set to perform their duet, the Salt-N-Pepa-referencing "Let's Talk." Between twirls, Maybach O took care to point out the shrieking ladies in the front row. Watch the performance above, and head over to vitaminwater's YouTube channel to see exclusive footage from all uncapped shows. With lots of surprise guests, uncapped is coming to six more cities and two college campuses later this year.
