Chance The Rapper put on for Chicago yesterday (Sept. 24) hosting his day-long Magnificent Coloring Day Festival in the Chi. Hip-hop heads in the city showed up and showed out at White Sox Stadium for the event which had scheduled appearances from Lil Wayne, Young Thug, 2 Chainz, Tyler The Creator, John Legend, Alicia Keys, Skrillex, Lil Uzi Vert and special guests. One of those special guest was Kanye West, who made the entire crowd lose its damn mind when he showed up unexpectedly.

In footage captured of the event, fans go nuts at the sight of West on stage and begin to pour from the stands down onto the field to get a closer view. In the clip, 'Ye raps "Father Stretch My Hands Pt 1" while what looks like hundreds of people hop over Porta Potties and sprint toward the stage. The whole scene literally looks like an outtake from World War Z.

The event also featured Chano unveiling his new non-profit organization Social Works Inc.

Chance and West have been in the lab working on new material recently. The "No Problem" rapper revealed he and West have two songs in the bag for their possible collab project Good Ass Job. “I know ‘Ye is working on something with Drake,” Chance said in a recent interview with Power 106. “We definitely have at least two songs I could say I know would be on Good Ass Job.”

He’s waiting to really hunker down in the studio with ‘Ye and work on the project.
