Did you enjoy Jay Z's (No hyphen anymore, people! Get it together!) grandiose banter in the Magna Carta Holy Samsung ads? Here's some more, in the form of a teaser for the "Picasso Baby" video, which Jay filmed in a six-hour marathon performance at Chelsea's Pace Gallery. The video will premiere on HBO — making the Carter-Knowleses two-for-two with the network this year — on Aug. 2 at 11 p.m., directly after Hova's appearance on Real Time with Bill Maher. Whether it will be a standard music video or a longer affair remains to be seen, but we can count on seeing Alan Cumming, Judd Apatow, and Marina Abramovic.
