At most huge pop tours, there’s a moment when shrieking fans reach a true fever pitch — when the lights dim right before the show begins, or when the intro to the artist’s biggest hit kicks in, or during the break before the encore. All of those happened at Olivia Rodrigo’s first arena tour — but her favorite part of the show was when those eardrum-rattling cries were, in fact, mad as hell.

“When we play ‘all-­american bitch,’ ” Rodrigo tells Billboard, “there’s a part at the end of the song where I ask the audience to think about something that pisses them off and then tell them to scream about it when the lights go off.” On the opener to her 2023 album, GUTS, Rodrigo juxtaposes folksy, facetious calm in the verses with enraged pop-punk in the refrain as she lays out society’s double standards for young women before unleashing a piercing wail. For nearly a hundred nights this year, the singer-songwriter has closed her main set by adding her own scream to an arena already full of them. “It’s definitely cathartic for me,” she says, “and I hope it is for the audience as well.”

The same could be said of the entire GUTS tour, where Rodrigo’s fans worldwide found the space to release their pent-up energy, as well as their excitement about one of the decade’s biggest new superstars. After bursting into the spotlight in 2021 with her debut album, Sour, and its No. 1 smashes “drivers license” and “good 4 u,” the former Disney+ TV star won the Grammy Award for best new artist in 2022 and quickly ascended to pop’s A-list. Yet the 2022 tour supporting Sour primarily played theaters, had to navigate lingering COVID-19 concerns and catered to a limited number of international markets, as Rodrigo, then 19, found her sea legs as a live performer.
