FLOW, a five-piece rock band whose twin vocal harmonies weave powerful melodies and whose wide musical range has yielded numerous classics, makes their Billboard Live debut. Debuting in 2003 with the single "Blaster," they have brought countless memorable songs to the world. They are also highly regarded for their affinity with anime works, and last year—their 20th anniversary year—they held an anime-song–themed concert at Makuhari Messe to great success, with buzz surrounding a world tour continuing into 2025. As they continue to rise, this show marks their first time on stage in an acoustic arrangement. In the intimate proximity unique to a club setting, what kind of chemistry will be born? It’s sure to be an unmissable night.
