The 2026 Lollapalooza act that released “Silk Chiffon” featuring Phoebe Bridgers in 2021 is MUNA. The song became one of the Los Angeles trio’s best-known tracks and a defining moment in their pop breakthrough.
MUNA released the single on September 7, 2021, after signing with Saddest Factory Records, the label founded by Bridgers. Its bright synth-pop production and openly queer love story gave the track a celebratory tone, while the accompanying video paid tribute to the 1999 film But I’m a Cheerleader.
“Silk Chiffon” led into MUNA’s self-titled third album, released in 2022. The band consists of Katie Gavin, Josette Maskin and Naomi McPherson. It is easy to confuse the answer with Phoebe Bridgers because she contributes vocals and appears prominently in the video, but the performing act and primary artist are MUNA.
