Japanese rock giants ONE OK ROCK made their long-awaited debut at London’s O2 Arena for one night only with an emotionally charged performance, showcasing their evolution into a powerful arena rock force. After two decades in the global rock scene, the outfit leaned heavily into their legacy, balancing longtime favourites with hard-hitting new material from their latest album DETOX, for a night of both nostalgia and reaffirmation of their present-day power.

Tom Grennan lit up the O2 Arena with an unforgettable performance that blended heartfelt warmth with undeniable star power. From the moment the Bedford-born singer-songwriter stepped on stage, the atmosphere was electric, charged with a raw, infectious confidence balanced by his trademark humility. Grennan managed to strike the perfect balance between spectacle and sincerity, transforming one of London’s largest venues into something that felt remarkably intimate, like a room full of friends.

Ariana Grande is officially heading back to the UK for her Eternal Sunshine Tour. The global pop icon has announced five headline shows at London’s O2 Arena in August 2026, marking her long-awaited return to the UK live stage after a six-year hiatus.
