The very first fusion band in Japan. The band is originated from the band formed by Akira Wada・Ken Watanabe・Daisaku Kume・Kohki Itoh・Katsutoshi Morizono・Rika Suzuki etc. in 1975. The band was selected as an opening act for the Eric Clapton's Japan tour in 1976. After heavy competition among record companies, the band signed with Polydor Records and released the 1st album “ PRISM ”.Upon its release, many fans queued up at the stores and sold out in many places. Following year, the debut concert was held at the Sugino Kodo Hall in Meguro of Tokyo. The fan made a line as long as it can reach Meguro station. It was such a sensational beginning for the band.

The Hollies' first album of original material following Graham Nash's departure was an attempt to regain the edge they'd had on Butterfly and Evolution albums, after the digression of the album of Dylan songs, the regrouping with Terry Sylvester in the lineup, and the unexpected hit achieved with "He Ain't Heavy, He's My Brother." It's a surprisingly strong album, not only in the songwriting (which includes the last Clark/Hicks/Nash song ever recorded, "Survival of the Fittest"), but also in the production, which isn't too far removed from what was heard on Butterfly and Evolution. There's no sitar here, but Tony Hicks – who is the real star of the group on this album – employs at least a half-dozen different guitars in uniquely fine voicings, and there is also some very striking use of orchestra, producer John Burgess making particularly fine employment of a string section as a lead instrument on the Allan Clarke/Terry Sylvester-authored "Man Without a Heart."
