[Machine Translation] A commemorative work for the 5th anniversary of KOKETSU HANABUSAKI's debut. Looking back over the past 15 years since her debut, KOKETSU Ayumi, a jazz alto saxophonist in her own right, has selected 23 pieces from her 9 albums and compiled them into this high-quality UHQCD 2-disc set. The warm and delicate yet core tone, the passionate and sometimes quiet voice, and the charm of her playing are all condensed in this definitive edition. The CD-only bonus track "Black Canvas" is an alternate take of an original song from the first self-produced album "Aquarelle," released in 2017. This rare and previously unreleased sound source will finally be unveiled for the first time. A total of 24 tracks tracing the trajectory of KOKETSU Ayumi, this is a must-buy album filled with the breath of 15 years of KOKETSU's career.
