Jay-Z staged a performance piece at Pace Gallery on Wednesday, rapping "Picasso Baby" for six hours to an eager crowd. While the event was initially kept under wraps, when Marina Abramovic got on stage with Jay-Z, the Internet blew up with Vines and Instagrams of the performance. Lots of other events also caused a social media storm this week, like Bernie Madoff's art sale, a Cat Gallery at White Walls, and Lady Gaga's announcing her latest art project. From KAWS' Brooklyn-based moonman for MTV's VMAs to Daft Punk condoms that read "Get Lucky," catch what you missed in art news with The Best Artist Instagrams of the Week.
