Lollapalooza is held in Chicago, which, as we all know, is Chance The Rapper’s domain. And yesterday, he held court at Grant Park, delivering a 20-song set that featured guest appearances from Vic Mensa and Francis & The Lights. Mensa came out to perform “Cocoa Butter Kisses” and his own “Didn’t I (Say I Didn’t),” while Francis assisted with his “May I Have This Dance (Remix)” and Chance’s “Summer Friends.” Watch some fan-shot footage below.
