Composer Sawano Hiroyuki, who has created music for popular works such as the anime Attack on Titan and the drama Iryu, will take the Billboard Live stage for the first time in about two years. He will welcome as vocalist SennaRin, whom he personally serves as total producer for, and will deliver a special performance based on 'PIANOUTA' from his latest album 'PIANOUTA / Project【emU】'. SennaRin, known for her naturally husky voice that delivers powerful vocals, is an up-and-coming singer who debuted in April 2022. Her track 'Saihate', released in November of the same year, was used as the ending theme for the anime Bleach: Thousand-Year Blood War, drawing attention. And 'PIANOUTA' is the collaborative album the two have eagerly produced, with a simple yet dense sound woven from piano and voice that stirs listeners' hearts. For this performance, delivered in an acoustic arrangement, experience the world of 'PIANOUTA' evolving in a one-night-only ensemble.
