Chance the Rapper surprised some high school students at his open mic event Monday night with a performance by grammy-winning artist Childish Gambino.

“My next guest needs no introduction,” Chance said before Gambino’sย hit single “This is America” started playing. Seconds later, once they recognized the track, students screamed and ran up to the front of the stage. Gambino came dancing out, wearing all white.
