You’d think after a decade in the industry, nothing would truly rattle a group of Hall of Fame legends. But when Sabrina Carpenter decided she wanted to bring out Earth Wind and Fire for her Lollapalooza 2025 headlining set, the "September" icons weren't exactly sitting around waiting for the phone to ring.
It was a total whirlwind.

Philip Bailey, the voice that has defined R&B for generations, later told Vulture that the entire collaboration came together in roughly 24 hours. Just one day. Imagine the logistics of that for a second. The band was actually in Detroit for a show on August 2nd. They had a tiny two-day gap before their next gig, and Sabrina’s team essentially moved mountains—and a private jet—to get the funk pioneers to Chicago’s Grant Park by August 3rd.
The Sabrina Carpenter Earth Wind and Fire Surprise
If you were in that Chicago crowd, the energy change was palpable. One minute, you're screaming the lyrics to "Espresso" or "Please Please Please," and the next, the iconic vocoder intro of "Let's Groove" starts vibrating through the floorboards.
Sabrina introduced them as her "friends from Chicago," which is a cute nod to the band's 1969 roots in the Windy City. They didn't just stand there and look legendary, either. They performed "Let’s Groove" and "September" with a level of chemistry that made the "sketchy and quick" rehearsal Bailey mentioned seem like a total lie.
Sabrina wasn't just a spectator on her own stage. She took specific verses, having clearly done her homework on the arrangements. She later shared on Instagram that the band "raised" her on the greatest songs of all time. Honestly, it’s a vibe that's becoming a bit of a signature for her. Just a month prior, she brought out Duran Duran in London. She's basically building a bridge between Gen Z pop and the heavy hitters of the 70s and 80s.
Why the "Man's Best Friend" Era Matters
This performance wasn't just a random festival stunt. It happened right as Sabrina was ramping up for her seventh studio album, Man's Best Friend, which dropped on August 29, 2025.
She’s been very vocal about how she went back to her roots for this record. We're talking heavy influences from Stevie Wonder, Dolly Parton, and Donna Summer. While the Short n' Sweet era was all about that tongue-in-cheek, wink-at-the-camera pop, Man's Best Friend feels a bit more soulful, a bit more lived-in.
- The Collaboration: It was initiated by Sabrina's agent.
- The Travel: A private plane was sent for the entire entourage to bridge the gap between Detroit and Chicago.
- The Rehearsal: Philip Bailey described it as "very quick" and admitted he was "almost concerned" about how it would go.
The gamble paid off. The "intergenerational music celebration" (as some fans called it on TikTok) proved that Sabrina has the vocal chops to stand next to Philip Bailey's falsetto without getting swallowed whole.
What Most People Get Wrong About the Collab
Some critics tried to claim this was a reaction to Olivia Rodrigo bringing out Weezer just two nights earlier on the same stage. Look, music festivals are competitive, sure. But you don't book a legendary R&B group with a massive touring entourage and a private flight in 24 hours just because you saw a tweet about Rivers Cuomo.

This was about Sabrina’s brand. She’s positioning herself as a "student of the greats."
There's a reason she didn't just sample them. She wanted them there. The difference is huge. A sample is a tribute; a live duet is an endorsement. By sharing the stage with Earth Wind and Fire, Sabrina Carpenter secured a stamp of approval from the old guard that most pop stars would kill for.
Behind the Scenes Logistics
Philip Bailey noted that Sabrina was "very cordial" and "approachable," but more importantly, he said she was "well-versed in the band's deeper discography."
That’s the detail that sticks. It wasn't a PR person telling her to like the hit songs. She actually knew the music. When they were backstage, they didn't have much time to hang, but the "compatible energy" was enough to carry them through a high-stakes livestream on Hulu.
It’s also worth noting the specific tracks they chose. "September" is essentially the unofficial anthem of every wedding and party on the planet. By performing it in August, Sabrina gave the crowd an "early celebration," effectively turning Grant Park into a massive disco.

The Cultural Impact of the Performance
We've seen a lot of pop stars try to lean on "retro" vibes lately. Sometimes it feels like a costume. With Sabrina, it feels more like an education.
When you look at the tracklist for Man's Best Friend, featuring producers like Jack Antonoff and Ian Kirkpatrick, you can see the threads of that soul-infused pop she was talking about. Songs like "Manchild" and "Sugar Talking" carry that rhythmic DNA that Earth Wind and Fire pioneered.
If you're looking to understand why this moment was such a big deal for her career, it boils down to three things:
- Credibility: You can't fake it next to Verdine White's bass playing.
- Market Reach: She brought parents and kids together in a way that feels rare in the 2026 landscape.
- Timing: It served as the perfect high-energy launchpad for her most ambitious album to date.
To really appreciate the connection between Sabrina Carpenter Earth Wind and Fire, go back and watch the fan-cam footage of the "Let's Groove" performance. Watch her face when the horns kick in. That’s not a pop star doing a job; that’s a fan living out a dream.
For those looking to dive deeper into her new sound, start by listening to her album Man's Best Friend with a pair of high-quality headphones. Pay attention to the bass lines on the track "My Man On Willpower"—you'll hear the direct lineage of the funk legends she shared the stage with in Chicago.
