The Strokes and they’re completely different because Charli xcx is there but also still The Strokes

Now The Strokes and Charli xcx are making rock music.

The pop star made a surprise appearance during Julian Casablancas and company’s headlining set at San Francisco’s Outside Lands festival over the weekend. She joined the band for a performance of the Is This It cut “Take It or Leave It.”

In introducing Charli to the stage, Casablancas congratulated her on having “defeated us at the album sales.” Both Charli and The Strokes put out new albums on July 24 — Music, Fashion, Film and Reality Awaits, respectively — with the former debuting at #3 on the Billboard 200 and the latter landing at #13.

Prior to sharing the Outside Lands stage, Casablancas collaborated with Charli on the song “Mean girls” off her 2024 remix album, Brat and it’s completely different but also still brat.

The Strokes have been touring the U.S. over the summer in support of Reality Awaits. Up next they’re heading to Japan to play the Summer Sonic festival before returning stateside for California’s Just Like Heaven festival on Aug. 22.
