After releasing SURF with Donnie Trumpet & The Social Experiment, Chance the Rapper has been busy preparing for the first Teens In the Park Festival, which took place this afternoon on Chicago's Northerly Island. The free festival was only available to young Chicagoans, ages 13 to 14, and it featured musical performances from Chance, Donnie Trumpet, DLow, and more young acts hailing from Chicago. 

During Chance's set, the audience was also blessed with an appearance from another youth hero, though one from out west: Kendrick Lamar. Not bad for a free show. 

Check out photos and footage of Kendrick and Chance on stage below.
