We've already seen quite a bit of footage from Coachella this year, in fact, you could stream all the performances from Day 1 and Day 2 if you were unable to attend in person. Nas brought out fellow rap stars Jay Z and Diddy during his "Illmatic" set at Coachella, while Pharrell brought out Tyler, The Creator, Nelly and Snoop Dogg, among others.
Girl Talk also had some surprises during his Friday night performance, with Busta Rhymes, Juicy J, Too Short and E-40 all taking the stage during their set, all of which you can view above. They took the stage prior to OutKast's reunion set, which you can watch in full here.
