Overview

• Earth, Wind & Fire joined Sabrina Carpenter’s Lollapalooza headline set on August 3 to perform “Let’s Groove” and “September” after only 24 hours’ notice.
• The band flew from Detroit to Chicago on a private plane at 7 a.m. for a same-day rehearsal ahead of the festival performance.
• Frontman Philip Bailey said he was initially “almost concerned” by the tight timeline but praised how the production was “dialed in” by evening.
• Bailey highlighted Carpenter’s preparation, noting she “did her homework” on her verses and described their energies as “very compatible and complementary.”
• The surprise duet continues Carpenter’s strategy of intergenerational collaborations as she builds momentum for her album Man’s Best Friend, due August 29.
