*200 copies limited edition* Born in 1954, Katsura Yamauchi is a saxophone player based in Oita, Japan. Since he began performing in earnest in the early 2000s, he has been touring and expanding his distinctive musical activities in Japan, Europe, North America and Asia. Koto player Kohsetsu Imanishi has an active career inside and outside Japan, performing music of various genres including classical Japanese music, improvisation and contemporary classical music. In addition to performing as a soloist and in performances with other musicians, she frequently collaborates with artists in fields ranging from visual art to dance to cinema.

Yamauchi and Imanishi appeared at Ftarri, Tokyo, on October 20, 2024, and gave an improvised duo performance. This album includes the two pieces (around 28 minutes each) from that concert. Yamauchi played alto sax. Imanishi played koto and, very briefly, singing bowl. As the title indicates, the two musicians' sounds interweave in a calm, natural fashion, like the flow of wind and water. A superb performance.
