Lollapalooza 2026: Olivia Dean Brings Out Sam Fender

Lollapalooza 2026 faced delays due to heavy rain in Chicago, but the festival proceeded with headliner Olivia Dean, who surprised the crowd by bringing out Sam Fender. The duo performed their record-breaking U.K. number one single, 'Rein Me In,' which recently surpassed a 70-year-old chart record.

Rain that flooded Chicago overnight and continued to fall on Saturday delayed the third day of Lollapalooza 2026 and caused organizers to push back doors by about three hours for cleanup. The downpours caused pooling throughout Grant Park where the festival is held. By the time it opened at 3 p.m., the grounds were understandably muddy, but navigable for attendees.
