They may have been two members down, but the pop group Katseye received a hero’s welcome as they played their first full concert in the UK.
The audience erupted with screams even before the show began, as the band broadcast their music videos on the O2 Arena’s big screens, and the noise barely dipped for the next three hours.
It was proof that Katseye have become pop’s biggest property (they’re currently the most-streamed act on YouTube UK) even while singers Manon Bannerman and Sophia Laforteza are on health-related hiatus.
The stage felt emptier without them, but their bandmates worked hard to fill the gaps, hyping up the crowd with a succession of bass-heavy pop anthems and jaw-dropping dance breaks.
“Are you happy to see us?” asked the band’s youngest member, Yoonchae Jeong, as if the answer hadn’t been obvious from the moment they appeared in a storm of laser lights and launched into the Brazilian funk workout of Hootie Frutti.
“I think you guys are our loudest crowd ever, literally,” marvelled Megan Skiendiel.
“This crowd is unbelievable,” added Lara Raj.
The concert was only the second date of the band’s Wildworld tour – but fans already knew every twist and turn from social media.
There was even a cheer of relief when Daniela Avanzini survived a complicated lift in the dance routine for Gabriella. On the opening night, her dance partner dropped her.
Such adulation – and scrutiny – has come quickly for Katseye.
Based in Los Angeles, the multinational girl group were only formed in 2023 as part of the online reality competition show The Debut: Dream Academy.
The contest was created by Hybe, the South Korean entertainment company behind acts like BTS and Le Sserafim, and the US record label Geffen, home to Olivia Rodrigo and the Rolling Stones. Of the 120,000 who initially applied for the show, only six made it through.
Trained under the rigorous K-Pop system, they had a breakout year in 2025, first with the hyperactive electro-skronk of their single Gnarly, then with its follow-up, a slinky ballad called Gabriela that highlighted Daniela’s Cuban-Venezuelan roots.
In London, their audience skewed young: The queue for pick and mix was longer than the one for the bar.
When Megan asked, “Whose first concert is this?” the air curdled with screams.
