On Thursday, July 28, 2026, in Chicago's Grant Park, Lorde performed as a headliner at the opening night of the Lollapalooza music festival. The event was marked by soaring temperatures, which led to several concertgoers passing out in the crowd. During her performance, Lorde noticed a fan in distress and paused her show to ensure that first responders could assist. This was not an isolated incident; she halted her performance at least three times throughout the evening to address the health concerns of her audience. Despite these interruptions, Lorde managed to keep the crowd engaged with her popular songs, including 'Royals' and 'Green Light.' She also surprised fans by inviting Charli XCX to join her on stage for their collaboration, 'Girl, So Confusing,' which received a warm reception from the audience. This performance marked Lorde's return to Lollapalooza, having previously performed at the festival in 2014 and 2017, where her set was cut short due to severe weather. The festival, which runs through Sunday, features a lineup of other notable headliners, including Charli XCX, The Smashing Pumpkins, and Olivia Dean, among others. The incident highlights the challenges of outdoor events during extreme weather conditions and raises concerns about the safety and well-being of attendees at large gatherings.
