Chance The Rapper, the best Chicagoan, regularly hosts Open-Mike Nights in Chicago. Only high school students get to come, and they get to develop their own skills, with Chance and sometimes with more famous guests looking on. Two years ago, Kanye West and Vic Mensa performed at one of Chance’s nights. And last night, he brought out once-reclusive comic genius Dave Chappelle, who did stand-up and took questions from the audience, at least if I’m hearing the murky fan-made video right. Check that video out below, via Pitchfork.
