The lineup for Chance the Rapper’s Magnificent Coloring Day festival included big names like Young Thug, Lil Wayne, John Legend, Alicia Keys, and Tyler, the Creator. And although those acts were plenty to get excited about it, there was one appearance that really made the crowd go wild. It was Kanye West.

During the Saturday event at Chicago’s U.S. Cellular Field, 'Ye stepped out for a surprise performance, and, naturally, this caused the crowd to rush to the stage. As seen in videos posted to social media, fans jumped from their stadium seats and ran to get a better look at Kanye’s set, which included performances of “Black Skinhead,” “Touch the Sky,” “Gold Digger,” as well as the Chance-assisted “Ultralight Beam.”

Earlier this month, Chance dished on Good Ass Job, his upcoming collaborative project with Kanye. Unfortunately for fans, however, Chance revealed it will be a while before we hear anything from the record.

"The Good Ass Job, that’s something that’s just been a dream for me," Chance said during an interview on The Cruz Show. "I’m a Chicago kid, so I’m a super 'Ye fan, and I used to watch all the, you know, YouTube videos and, like, him speaking. And I remember just watching a video a long time ago where he would go on, he was explaining, you know, how you have your college dropout, and then you go back you have your late registration, and then you finally get your graduation. And after you graduate, you gotta go get a good ass job."
