On Wednesday night, Kanye West put on a surprise performance in New York City for those who were invited to the Samsung Galaxy Note II launch. Yeezy hit the stage towards the end of the night and performed several tracks, including "Clique," "New God Flow," "Mercy," "Jesus Walks," "Good Life" and "Say You Will." Things were taken up a notch when the G.O.O.D. Music front man brought out 2 Chainz to perform their collaborative track "Birthday Song."
