Since his major debut in July 2012 with the mini-album "Symphony of the Third Planet," the singer-songwriter Ishizaki Hyuui has continued to be active not only in his own music career but also as a prolific songwriter who has provided numerous songs and as an actor. With a vocal style that seems to be sung with his whole body, catchy melodies, and lyrics that convey real emotion and an original, imaginative worldview, he is returning to Billboard Live in the "piano quintet" arrangement that drew favorable reviews last year. In a space adorned with arrangements unique to this performance, please fully experience his music, which continues to evolve beyond ten years since his debut.
