LE SSERAFIM Ignited Ablaze the 2026 iHeartRadio Music Festival — And Made K-Pop History

LE SSERAFIM Made iHeartRadio Festival History — Then Set the Stage Off

LE SSERAFIM ignited ablaze the 2026 iHeartRadio Music Festival — and made a little history while doing it. The group became the first K-pop girl group to perform at the festival when Sakura, Hong Eunchae, Kazuha, Huh Yunjin and Kim Chaewon took the stage on night two at T-Mobile Arena in Las Vegas.

That milestone already gave the set some extra electricity, but the performance itself did the rest. LE SSERAFIM moved through “Made My Night,” “Iconic By Mistake,” “Saki,” “SPAGHETTI,” “CRAZY” and “BOOMPALA”, bringing their usual precision-heavy choreography and pop muscle to one of iHeartRadio’s biggest live stages.

“BOOMPALA” gave the performance an especially cheeky pop-culture turn. The track samples Los del Río’s 1993 mega-hit “Macarena,” and the group folded the familiar choreography into their own stage routine — a very LE SSERAFIM way of taking something instantly recognizable and making it feel newly theirs.

The festival appearance lands as LE SSERAFIM continue the North American leg of their PUREFLOW world tour, supporting PUREFLOW, pt. 1. That makes the iHeartRadio stop feel less like a one-off booking and more like another marker in how quickly the group’s U.S. footprint keeps expanding.

And while the “first K-pop girl group” headline is the obvious history-book line, the set works because it does not lean on the milestone alone. LE SSERAFIM showed up with the songs, choreography and stage confidence to make the distinction feel earned rather than ceremonial.

History made. Stage handled. Very little left on the floor.
