Chance The Rapper hosts "Open Mike" event twice a month in his hometown Chicago. The closed-door event is open to high school students of the Windy City. During last night's show (May 12), the young rapper brought fellow Chi-town natives Kanye West and Vic Mensa on stage to perform for the kids, which looked like the best surprise ever.

During their segments, Kanye performed "All Day" and "We Don't Care" off The College Dropout, while Mensa held the stage down by performing "U Mad." Fans caught a lot of video footage, which you can check out below.

As far as Chance was concerned, the night was a success.
