Yesterday the first day of Jay Z's 'Made In America' festival went down in Philadelphia. As the concert was nearing it's end, Kanye West and his G.O.O.D. Music crew surprised the crowd with a group performance.
Kanye, Pusha T, Big Sean, Common, and 2 Chainz performed recent singles, "Mercy" and "New God Flow," along with each performing a few of their own tracks.
