Shutsumin, the debut recording from the generation spanning duo of Japanese legend Otomo Yoshihide, toggling between guitar and turntables, and rising saxophonist Kei Matsumaru, a native of Papua New Guinea, who moved to Tokyo after studying jazz at the Berkelee College of Music in Boston, where he's become a close collaborator of Eiko Ishibashi in addition to leading his own genre-defying solo projects. Both musicians casually ignore lines between jazz, experimental music, and noise, fashioning a bracing set of improvisations marked by visceral timbres, quicksilver gestural exchanges, and charged interactivity.
