The least formal upfront of the week, Adult Swim capped Wednesday night with a function at the Roseland Ballroom that was more like a concert than a sales presentation with Jay-Z entertaining the crowd.

Earlier this week it wasreported that the Grammy-winning rapper will partner with the Turner network on a project, a venture that has yet to be officially announced.

Jay’s friends and peers Pharrell, Ne-Yo, Kid Cudi, and Fabolous were also on hand to rock with him on the night!
