Among the big draws were Sabrina Carpenter, who closed out the festival with surprise guests Earth, Wind & Fire, and A$AP Rocky, who performed from a life-sized helicopter onstage. The Marías, Dominic Fike, and Finneas were among the highlights from the Chicago fest’s final day on Sunday at Grant Park.

On the final night of Lollapalooza, one of the festival's biggest headliners brought out music legends to help the crowd just "let loose and groove."

Carpenter is now gearing up to release her new LP, Man's Best Friend, on Aug. 29. The project was led by Billboard Hot 100 -topping single "Manchild," and just a couple of days prior to her Lolla set, the star unveiled the album's full tracklist. Sabrina Carpenter ‘s signature "Juno" arrest had TWICE the star power at Lollapalooza over the weekend.
