Pitchfork Music Festival-goers were treated to a pretty big hometown surprise during AraabMuzik's set this past Sunday. He brought out Chicago's own Chief Keef, Lil Reese, and Young Chop to perform their smash single "I Don't Like." You can watch some footage of the performance above, though you'll have to squint to see Keef, Reese, and Chop getting down onstage.
