While holding a benefit concert for the Museum of Modern Art’s annual party in the Garden, Kanye West performed a medley of songs including "Good Life," "Runaway," and "Flashing Lights." Towards the end of his set, big bro Jay-Z made a surprise appearance and they performed "H.A.M." right before Jigga man took the stage for "Empire State Of Mind." Sounds like another good Yeezy show. Watch some short footage of the event above.
