Once a month Chance the Rapper’s charity, SocialWorks, puts on an “Open Mike” (named in honor of Brother Mike Hawkins) in collaboration with Chicago Public Library. There have been 27 Open Mikes so far, with over 6,000 attendees and star studded lineups, having featured appearances from Vic Mensa, Kanye West and yesterday Childish Gambino was added to that list. Gambino came out and performed his hit “This Is America” with full choreography.
