Charli XCX performed her 2014 breakout single “Boom Clap” with guest Chappell Roan at the Kia Forum in Los Angeles on Saturday night, according to Variety and Rolling Stone.

What happened

The Kia Forum show was the second night of Charli XCX’s Music, Fashion, Film tour, which began in Philadelphia on September 11 and includes two dates at the Forum. During the set, Charli announced that she had asked a friend to join her for an old song, and Chappell Roan answered the request. The duo sang “Boom Clap,” the first time Charli has performed the track live since 2023, as noted by setlist.fm. Later in the evening, Charli brought out PinkPantheress for her song “Stateside,” and the Dare performed an extended version of “Guess,” complete with cannons firing pairs of underwear into the audience.

What the reports add

Variety reported that the performance was prompted by a “special request” from Chappell Roan, who joined Charli onstage for the song. Rolling Stone echoed Charli’s quote about asking a friend to sing an old song and added that the “Boom Clap” duet marked the first live rendition of the 2014 hit in the current Brat/Music, Fashion, Film era. Both outlets described the subsequent guest appearances, though Variety mentioned the Dare’s “extended version of ‘Guess’” while Rolling Stone specified it was the Billie Eilish remix of the track.

What was said

Charli XCX told Variety, “Every night on tour, I play an old song. I asked a friend of mine if she would come and sing an old song of mine with me, and they said, ‘The only way I’m doing it is if it’s this song,’ so you have her to thank.” Rolling Stone quoted the same statement, attributing it to Charli during the Kia Forum concert.

How it came about

Charli XCX’s tour supports her July 24 album Music, Fashion, Film, which shifts toward guitar‑based sounds. The surprise appearance of Chappell Roan follows her own upcoming “Super Graphic Spectacular” benefit concerts at the Shrine Auditorium on October 21‑22, a event Felo previously covered here. The tour’s Los Angeles stop also featured other guests, continuing a pattern of collaborative moments that began with a surprise Tinashé appearance at the Austin City Limits Festival, as noted by Rolling Stone.
