Kanye West surprised fans at the second annual Odd Future Camp Flog Gnaw Carnival, where he jumped on stage with Tyler, the Creator to perform "New Slaves" and "Late," which he admitted he hadn't done in six years. The G.O.O.D. Music rapper seemed to be having trouble with remembering the lyrics, but Tyler lent a helping hand, as he knew it word for word. 

Other performers at the carnival included Mac Miller, Flying Lotus, ScHoolboy Q and OFWGKTA members Earl Sweatshirt, The Internet, Frank Ocean. Check out the above slide for more photos:
