Jay-Z is in full-on promotion mode for his new album Magna Carta Holy Grail, it seems. After participating in a Twitter Q&A with fans, HOV's next venture was to perform (our favourite) track from the new record,  the aptly titled 'Picasso Baby', for six hours straight in New York City's Pace Gallery.

This six hour gallery show idea seems to be quite in vogue lately. The National performed their song 'Sorry' from new album Trouble Will Find Me for six hours straight in MOMA in New York on May 5th last.

Guests at the Jay-Z performance included film director/producer Judd Apatow and Girls actor Adam Driver.
