The opening of the pair of simultaneous releases, "Introduction," is a new wave of free jazz born from an intergenerational improvisation session with Takashi Sugawa (b) and Shun Ishiwaka (ds). Guitarist/composer Otomo Yoshihide has been active all over the world, from movies, plays, TV to commercials, without being confined to the framework of free jazz. The live recording of December 27, 2024 at Shinjuku Pit Inn, which has been his "core" since his teenage years, is not only a "milestone" in Otomo's career, but also a dense documentary that condenses the past, present, and future of the Japanese jazz scene in a single sitting. It is also a documentary that condenses the past, present, and future of Japan's jazz scene in a single sitting. This improvisation project is titled "Introduction" and "Break", which are essential concepts of Noh (Bugaku), and what kind of scenery will be created by Otomo's hands in the future?
