Yesterday Jay Z performed “Picasso Baby” for 6 hours straight in the New York’s Pace Gallery for an art exhibit and filmed it for a music video.Promoting for his new album out “Magna Carta Holy Grail.”. On site was Mark Romanek who directed his “99 Problems” video. DAM 6 hours straight of the same song that must of been tough. People were being let in on hour long shifts to see Jay perform. This was big on social media like twitter and vine and instagram.
