The Yoshihiro Kai Billboard Live Series, which celebrated its 10th anniversary last year, opens again this year. As it enters a new decade, it will surely take the audience to a special moment, built on the maturity accumulated over the years and on fresh, unconventional ideas that don’t fit the mold. Backed by a deep understanding of Americana and the high level of musicianship to express it, the performances will unfold with a rock‑minded energy. In contrast to the parallel Kai Band 50th Anniversary Project, the vivid acoustic lineup will let listeners savor Kai’s vocal charm.
