Chance The Rapper promised special guests at his inaugural Magnificent Coloring Day festival in Chicago yesterday, and while the announced lineup was stacked with artists like Tyler, The Creator, Lil Wayne, and so many others, the crowd at U.S. Cellular Field absolutely freaked out when they saw Kanye West on stage for a surprise performance.

In the clip below, you can see hordes of fans running towards the stage as Kanye performs "Father Stretch My Hands Pt. 1," with people hopping over Porta Potties and anything else in the way to get as close to the stage as possible.

Kanye's performed a medley of his hits including “Black Skinhead,” “Can’t Tell Me Nothing,” “Touch The Sky,” “Gold Digger,” “Father Stretch My Hands Pt. 1,” “Pt. 2,” and his verse from Schoolboy Q’s “THat Part.” He was also joined by Chance for "Ultralight Beam."

Watch Kanye and Chance's performance of "Ultralight Beam" below, as well as footage of the excited crowd rushing the stage.
