Lorde Halts Lollapalooza Set as Fans Collapse in Heat

Lorde stopped her Lollapalooza headline set Thursday night after several fans near the front of the crowd at Grant Park passed out, forcing Lorde to call for security three separate times while medical crews worked their way through the packed audience.

The interruption came during the festival's opening night, with temperatures still sitting in the mid-80s when Lorde took the T-Mobile stage. Many of the fans closest to the barricade had been standing in that spot for roughly 10 hours, having rushed the grounds when gates opened that morning to claim a view of the headliners. By the time Lorde performed, the combination of heat, humidity and a tightly packed crowd left several people unable to stay upright.

An NBC Chicago producer at the show said fans near the front began losing consciousness as Lorde performed, prompting her to pause the set. Rather than leave the moment awkward, Lorde filled the gaps in her show by talking to the crowd about her history with Lollapalooza and her connection to Chicago, repeatedly telling fans to drink water and stay hydrated while EMTs and security staff moved through the crowd to reach the people who had gone down.

"I've been so nervous all day," Lorde told the audience. "I really care about Chicago, I really care." She first played the festival in 2014 at age 17 and returned Thursday calling it "completing the circle" after her 2017 headlining set was cut short after only three songs because of severe rain.

Once the medical response cleared, Lorde resumed the show and delivered a set built around songs like "Team," along with a surprise appearance from Charli xcx for a performance of "Girl, So Confusing" that confirmed rumors circulating on social media earlier in the day. The crowd, among the largest gathered that afternoon at Grant Park, had been building for hours before her scheduled start time as temperatures stayed high through the afternoon.

The heat was a running theme across the first day of the festival. Performers repeatedly acknowledged it from the stage, with Between Friends singer Savannah Hudson telling the crowd at the Bud Light stage it was "hot in here" hours before Lorde's set. Festivalgoers sought shade near Lake Michigan, lined up for iced coffee and cooling stations at sponsor tents, and packed the shaded areas around the grounds' new attractions, including a Ferris wheel at the north entrance that needed about an hour of maintenance during the afternoon.

The weather did not ease up as the weekend went on. By Friday, forecasters were warning of storms moving into the area, with meteorologists predicting repeated downpours through the evening. The shift in conditions led organizers to cancel Lil Uzi Vert's set ahead of Friday night headliner Charli xcx, with a message projected on screens at the festival citing "weather issues." The storms also forced cancellations of outdoor events across the suburbs and into northwest Indiana, including movie nights in local parks and concert series in towns including Elgin, Niles and Schaumburg. Heavy rain later flooded several roads in Joliet, prompting city officials to warn drivers to use extreme caution.

Lollapalooza organizers have not detailed how many people required medical attention during Lorde's set or whether any were hospitalized. The festival's standard protocol includes water stations and shaded rest areas throughout Grant Park, along with medical tents staffed for heat-related illness.

Lollapalooza is scheduled to run through Sunday in Grant Park.
