Two itinerant and unique performers in solo and small group configurations--Japanese saxophonist Katsura Yamauchi, who has recorded & performed with Voice Crack, Tatsuya Nakatani, Otomo Yoshihide, &c. &c., and Swiss electroacoustic improviser Jason Kahn--meet during Kahn's 2023 visit to Japan, recording these perceptively subtle duos live at HALL, in Oita and at IAF SHOP, in Hakata.
