Billie Eilish, O2 review - power, authenticity and deep connection

Billie Eilish may be one of the biggest names in new music, but here at the O2 Arena, she’s just Billie – the one who stares deep into your soul, smiles at you like she knows your secrets, and shouts “I love you” like she means it. “You are seen, you are safe,” she tells us. We believe her. And judging by the thousands of utterly hysterical fans, heaving and shaking with sobs amidst their singing – mostly clad in jorts, sports vests and ties – the feeling is mutual.

The 23-year-old pop sensation first appears crouched in the centre of a metal cube, dangling above the crowd, instantly evoking the lyric, “Step off the stage, I’m a bird in a cage” from her song, “Skinny”. She is a spring coiled and ready to unleash max emotional chaos, breaking into the eerie house beat of “Chihiroh”, rolling through the driving “Lunch” and straight into the propulsive, strobe-lit “NDA”.

With the stage centred in the auditorium, everyone has a front-row feeling. There are no gimmicks, no dancers, no flamboyant costumes or changes, no chitchat – just Eilish in her signature baggy basketball attire, sometimes a cap, some calf-length pop socks, radiating a quiet defiance. Her connection with the crowd is the main event.

Often, she simply stands at the edge of the stage, just smiling at her fans, as if telepathically communicating with them. A selfie stick captures extreme close-ups of her intense eyes – wide, vulnerable, occasionally haunted (“The Diner”) while she pans the band and audience during “Bad Guy”.

The set oscillates between pounding bangers (raunchy Charli XCX collab “Guess”), rage songs accompanied by bursts of fire and kneeling solo electric guitar (“Happier Than Ever”) and raw, slow-burn confessionals. But it’s the stripped back, tender acoustic moments that give lingering tingles. Sitting cross-legged centre stage, Eilish asks her fans for a moment of absolute silence so that she can loop her own humming for the backing vocals of “When the Party’s Over” – a moment of intimacy that sees her lying on her back on a blanched white stage singing “Let’s just let it go, Let me let you go”. “The Greatest” is a standout: an absolute belter that sees 20,000 souls across the auditorium being channelled in soaring crescendo.

“Your Power,” is played softly on her guitar and dedicated “to all those suffering right now,” before a pure rendition of “Moon River” in an acoustic circle. “Ocean Eyes” gets the tears going again, then the arena turns pink for the quiet devastation of “What Was I Made For?” as Eilish sits on a little ledge, feet swinging from the reaching hands of her fans, before “Birds of a Feather” as the final offering.

Eilish doesn’t need spectacle – her power comes in restraint. Strip away the showmanship and all that remains is voice, presence, and connection. The result is human, heartfelt, and deeply hysteria-inducing. Maybe it resonates so deeply because in an increasingly extra world, she is proof that the most radical act might be simply showing up as yourself.
