BTS Closes iHeartRadio Festival Night 1 With 'BTS 2.0' Set — Fans Slam 16-Minute Slot

September 18, 2026 — BTS closed out night one of the 2026 iHeartRadio Music Festival at T-Mobile Arena in Las Vegas, their first appearance at the festival in six years, with a four-song, roughly 16-minute set from 'ARIRANG': 'SWIM,' '2.0,' 'MIC Drop' and 'FYA.' The set was staged under a 'BTS 2.0' theme — an LED aquarium with surging water for the opener, a Las Vegas skyline and universe-tunnel visual sequence, and a closing effect of seven comets colliding with desert flames. The group ended by telling the crowd ARMY are 'truly the best fans in the world.' The performance was broadcast live on iHeartMedia radio stations and streamed on Disney+ and Hulu alongside a lineup including Cardi B, Snoop Dogg, Kenny Chesney and Benson Boone. In the hours after, ARMY on social media criticized the festival's handling of the set — its length relative to other acts' roughly 30-minute slots, an abrupt ending with no encore, and complaints about sound mixing, camera coverage and lighting; neither iHeartRadio nor HYBE addressed the criticism publicly. BTS's next stop is the Latin American leg of the ARIRANG World Tour, opening Oct 2 in Bogotá.
