The first leader album by Ryo Kawasaki, a jazz and fusion guitarist whose talent was recognized by Gil Evans and who went on to work internationally. The album presents a cool cosmic sound, including "Agana," where Kawasaki delivers breath-taking guitar playing over high-speed percussion, and the dazzling jazz-funk number "Phil."

East Wind was a ground-breaking jazz label established in 1974 through the full cooperation of Ai Music, as it was then known, and Nippon Phonogram, as it was then known. Over a period of about five years, the label produced albums not only by Japanese musicians such as Masabumi Kikuchi, Sadao Watanabe, and Terumasa Hino, but also by musicians who were engaged in creative activity on the global jazz scene at the time. In addition to the quality of the performances, the artwork, created with leading designers and photographers, brought a fresh new image to jazz albums and had a major influence on later record production.
