Lorde briefly halted her Lollapalooza headline performance in Chicago after several audience members near the stage reportedly lost consciousness in the heat. The pause allowed security to assist those affected, highlighting the risks posed by crowded festival conditions during hot weather.

The incident occurred on the festival’s opening night, Thursday 30 July. Lorde performed songs including “Royals”, “Supercut”, “Green Light” and “Ribs”, and was joined by Charli XCX for “Girl, So Confusing”; it was Lorde’s first Lollapalooza appearance as a headliner after performing there in 2014.
