Rapper Jay Z's 10-minute Picasso Baby promo, which debuted on Tv in America on Friday night (02Aug13), was edited down from almost 30 hours of footage, according to director Mark Romanek, who also shot the hip-hop star's 99 Problems video. The performance art piece, filmed at New York's Pace Gallery for six hours straight on 10 July (13), was based on Marina Abramovic's The Artist Is Present Museum of Modern Art performance and film. She was among the guests who appeared in the film.
