Last night Jay-Z took the stage at the in New York.  The event he was performing at was Cartoon Network’s Adult Swim upfront soiree, which took place at Roseland Ballroom.  The event featured a performance of Jay-Z’s track “Thank You” over The Boondocks intro theme.  AdWeek reports that sources at the owners of Cartoon Network’s Adult Swim, Turner Broadacsting, confirmed a partnership between Jay-Z and the network although details remain scant. Jigga also performed at the event with his hair cut and he is known for saying that he only cuts his hair when a project is done. Watch The Throne coming soon?
