As if that exclusive album release date for one million Samsung Galaxy owners didn’t generate enough attention for Magna Carta Holy Grail, superstar rapper Jay-Z is spending six hours today performing “Picasso Baby,” a single off the album.

Jay is performing in front of an invite-only crowd at Pace Gallery in New York City’s Chelsea neighborhood, studded with famous faces such as director Judd Apatow, Girls actor Adam Driver and Girls costar Lena Dunham’s mother.
