CORTIS Makes Its Lollapalooza Debut Saturday. An Aftershow Follows the Night Before.
CORTIS plays its first Lollapalooza set Saturday afternoon at Grant Park, the only K-pop boy group booked for this year's festival, before following it with an official aftershow at House of Blues Chicago.
The group - Martin, James, Juhoon, Seonghyeon and Geonho - takes the stage Saturday, Aug. 1, from 2:55 to 3:45 p.m. Central time, part of a bill headlined that day by Olivia Dean and John Summit. Lollapalooza runs Grant Park from Thursday through Sunday this year, with aespa, i-dle and Jennie also on the four-day lineup - meaning five separate K-pop acts are playing the festival, though CORTIS remains the only boy group among them.
Schedule:
Friday, July 31 - Official Lollapalooza Aftershow, House of Blues Chicago
Saturday, Aug. 1, 2:55-3:45 p.m. CT - Lollapalooza main lineup, Grant Park
Tickets:
Lollapalooza 4-day and single-day passes: Required for Saturday's main-stage set; entry gates open at 11 a.m. and close at 10 p.m. daily
Live Nation - CORTIS Lollapalooza Aftershow, House of Blues: Separate ticket required for Friday night's standalone show, not covered by a festival wristband
The booking follows CORTIS's run of 2026 milestones: the group became the first K-pop act to headline the NBA Crossover Concert Series' Opening Night at NBA All-Star weekend in February, and this week Big Hit Music confirmed the group passed 1 billion cumulative Spotify streams - the fastest pace ever recorded for a K-pop boy group. CORTIS's debut EP, "Color Outside the Lines," reached No. 15 on the Billboard 200 last year, and this year's follow-up, "Greengreen," debuted at No. 3.
CORTIS's own North American tour, "Put Your Phone Down," opens Aug. 4 in Toronto - meaning the Lollapalooza and House of Blues dates double as a warmup for a run that already sold out both its Incheon and North American legs before a single ticket went to general resale.
