, 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 (ja) 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 had released over 40 albums in Japan and around the world. Starting from 2012, they formed Casiopea 3rd as a spin-off from the original, featuring Kiyomi Otaka on keyboards and returning members, Issei Noro, Akira Jimbo, and Yoshihiro Naruse. On July 1, 2022, it was announced that Yoshinori Imai would be the band's new drummer after Akira Jimbo left Casiopea 3rd, and the band would be rebranded as Casiopea-P4. History Casiopea 1st (1976–1989) One of the band's earliest appearances was at Yamaha's amateur band contest "EastWest '76" (ja), featuring Issei Noro, Tetsuo Sakurai, Hidehiko Koike, and Tohru "Rika" Suzuki. This was Casiopea's original formation, and both Koike and Suzuki left the band due to being busy with other projects at the time (Suzuki joining Prism, and Koike in other bands). They finally got their first permanent formation when Takashi Sasaki replaced Suzuki on Drums and Minoru Mukaiya replaced Koike on Keyboards in 1977. They would re-appear in the "YAMAHA EastWest '77" contest at this time, and they later made their official live debut in January 1978. Around this time, musicians like Prism guitarist Akira Wada, keyboardist Jun Fukamachi, guitarist Kenji Omura and others in the Japanese Fusion scene frequently appeared with the band as supporting members/special guests in some of their live performances (with their appearances ranging from 1977 to 1979, and 1980 for some). The first label to sign them was Alfa Records, which released their album Casiopea, which was released in May 1979, featuring the Brecker brothers and David Sanborn as the brass section. They would also release the album Super Flight later that same year. After the end of the Super Flight tour in January 1980, Sasaki also left the band and Akira Jimbo would fill the drummer seat in the following month. "Galactic Funk" appeared on their 1981 album Cross Point (1981) with ten different versions recorded both live and in studio. The album Eyes of the Mind
