Casiopea , now known in its fourth iteration as Casiopea-P4, is a Japanese jazz fusion band formed in 1976 by guitarist Issei Noro, bassist Tetsuo Sakurai, drummer Tohru "Rika" Suzuki, and keyboardist Hidehiko Koike. In 1977, keyboardist Minoru Mukaiya and drummer Takashi Sasaki joined, replacing Koike and Suzuki. They recorded their debut album Casiopea (1979) with guest appearances by American jazz musicians Randy Brecker, Michael Brecker, and David Sanborn. In 1980, drummer Akira Jimbo joined the band. Casiopea has released over 40 albums in Japan and around the world.

David William Sanborn was an American alto saxophonist. Though Sanborn worked in many genres, his solo recordings typically blended jazz with instrumental pop and R&B. He released his first solo album Taking Off in 1975, but had been playing the saxophone since before he was in high school and was a session musician long before its release. He was active as a session musician, playing on several albums by various artists.
