Lorde paused her Lollapalooza headline show on Thursday after several fans passed out in the crowd.
During her performance on the music festival’s first night, Lorde briefly stalled the show because fans near the front of the crowd were losing consciousness, according to an NBC Chicago producer at the show.
The pop performer called for security at least three times to help the fans.
Her headline show drew massive numbers of the hundreds of thousands of music fans in attendance and those at the front were likely there since the gates opened roughly 10 hours prior.
Sky 5 was over Grant Park Thursday morning as some fans ran to the main stages to save a spot to see the headliners, including Lorde and Chicago’s own John Summit.
In addition to the tightly packed concert space, temperatures were still in the mid-80s when her set started.
