In an interview with Vulture on Tuesday, Aug. 5, Earth, Wind & Fire’s Philip Bailey opened up about how the group’s performance with Sabrina Carpenter came together so quickly.

It was very quick and kind of sketchy,” says Philip Bailey of their Lollapalooza surprise. “I was almost concerned about it.”

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.
