Last month, Jay Z stopped by the Pace Gallery in NYC to perform “Picasso Baby” for six straight hours, rapping directly into the face of attendees one at a time. The “performance art piece” was documented for a music video of sorts, in the form of a short film titled Picasso Baby: A Performance Art Film. The short film aired last night on HBO. It starts end ends with interviews with Jay Z, and features appearances by various attendees of the event including Marina Abramovic (who inspired the piece), Judd Apatow, Pablo Picasso’s granddaughter Diana Widmaier Picasso, and others.
