Aging rapper Jay Z put his narcissism on display at a Manhattan art gallery on Wednesday. The 44-year-old rapper lip synced his track “Picasso Baby” for 6 hours at Pace Art Gallery. The publicity stunt was intended to help boost sales of his twelfth studio album, Magna Carta Holy Grail. The album shipped platinum thanks to the 1 million advance copies purchased by Samsung to give away for free to Samsung Galaxy owners.

During his 6-hour repetitive performance of the same song, Jay Z invited observers to join him. Beyonce’s husband cheered on a break dancer, and at one point he was joined by performance artist Marina Abramovic.

A Complex magazine editor captured more Vines of Jay Z’s mind numbing performance after the break.
