LE SSERAFIM kick off first European tour with sold-out London concert at The O2

LE SSERAFIM began their first European tour at London’s The O2 on 16 October, playing to a sold-out crowd of over 15,000 vociferous fans after overwhelming demand prompted the release of additional seats.

The concert opened 2026 LE SSERAFIM TOUR ‘PUREFLOW’ IN UK & EUROPE, taking the group’s second world tour into a new territory following shows in Japan and nine North American cities. SOURCE MUSIC confirmed the London sell-out on 13 October, ahead of the extra seats becoming available.

For the quintet, the occasion brought two milestones together: their European tour debut and the approaching fourth anniversary of 'ANTIFRAGILE'. Released during their debut year, the song provided a point of connection between their early career and a night spent performing to thousands of fans in London.

Onstage, the group delivered the tightly coordinated choreography and energetic live performances that underpin their concert repertoire. Offstage, they documented a less formal introduction to the city, sharing soundcheck preparations alongside streetwear snapshots and visits to landmarks including Big Ben.

The London date follows a busy stretch on the road. PUREFLOW began at Incheon’s INSPIRE Arena in July, before travelling through Japan and North America. Its European itinerary continues through Amsterdam, Paris, Copenhagen, and Berlin.
