Chicago, IL – High schoolers at the Harold Washington Library Center in Chicago, Illinois got a special treat on Monday (June 11). Childish Gambino (aka Donald Glover) stopped by to perform his hit song “This is America” for the students attending Chance The Rapper’s Open Mike Chicago event.

Chance — who has been teasing the possibility of a joint mixtape with the Atlanta creator for some time now — told the crowd his next guest needed no introduction. Soon after, the crowd began rushing the stage as “This Is America” began to play over the speakers.

The Open Mike event, which is put on by Chance’s SocialWorks charity, is designed to encourage youth participation in the arts.
