Big Sean pulled into Florida International University on Wednesday for a co-headlining gig with Gym Class Heroes at the Uproar Concert 2012. In addition to his solo hits, the G.O.O.D. Music rapper performed his verse off the G.O.O.D. Music single “Mercy” for one of the first times. The college crowd already knew the lyrics, rapping along as Sean bounced around the stage. Swerve!
