For six hours Jay-Z performed ”Picasso Baby” at New York City’s Pace Gallery in front of selected fans, artists, collaborators, friends, and media yesterday (July 11). Hov has been on a rampage since dropping his Magna Carta Holy Grail this past Tuesday (July 9). He’s done a string of interviews, most recently with Power 105.1′s The Breakfast Club, and a impromptu twitter Q & A. His performance is going to be in a docu-music video for the song. Special guests which we’re there reportedly included Wale, Judd Apatow, Marina Abramovic, Girls star Adam Driver and Girls actress Lena Dunham’s mom.
