Chappell Roan Booked a Tour. Then She Blew Up.

In September 2023, Chappell Roan opened the tour for her debut album, “The Rise and Fall of a Midwest Princess,” in Sacramento at the Goldfield Trading Post, a venue that holds 600 people.

Last Friday night in Seattle, she held court before a festival crowd of 10,000 at the Capitol Hill Block Party. And lately, 10,000 is a small crowd for the rising pop star.

The narrow street where the event is held couldn’t contain all the fans who arrived in glittery pink cowboy hats — a homage to Roan’s song “Pink Pony Club,” about dancing at a gay bar — so those without tickets camped out at an adjacent gas station and sang along to synth-pop hits like “Good Luck, Babe!” and “Hot to Go!,” both of which have been climbing Billboard’s Hot 100 in the past six weeks.

The last few months have been transformative for Roan, 26, who released her first EP in 2017, was dropped by her label in 2020 and then began a fruitful collaboration with the songwriter and producer Daniel Nigro (Olivia Rodrigo, Sky Ferreira). Since she looked directly into the camera at the Coachella festival in April and declared, “I’m your favorite artist’s favorite artist,” she has seemingly been everywhere — on TikTok, YouTube, talk shows, NPR’s Tiny Desk.
