Rap and entertainment superstar Tyler, the Creator served as the opening night headliner for the Lollapalooza Music Festival in Chicago's Grant Park on Thursday night, but he was almost forced to cancel his performance.

In a brief hourlong set, the rapper packed in new and old jams. In addition to a platter of “Don’t Tap the Glass,” there was a big spotlight on “Chromakopia” and its verbose tracks like “Rah Tah Tah” and the fan favorite lick of “Sticky.

Luke Combs will be Lollapalooza’s first-ever country festival closer, across Grant Park from Tyler, the Creator.
