A heretical masterpiece with an overwhelming presence in the history of Japanese jazz. Jiro Inagaki was one of the central figures in the development of jazz rock in Japan. Inagaki, who had doubts about the existing jazz music, turned the helm to jazz-rock at once with this album recorded in 1970. From the opening track "The Vamp" to the closing "Head Rock," Inagaki poured all his ideas and passion into this jazz-rock album that leaves no time to exhale.Jiro Inagaki (Tenor Sax)Tetsuo Fushimi (Trumpet)Ryo Kawasaki (Guitar)Masaru Imada (Organ)Yasuo Arakawa (Bass)Sadakazu Tabata (Drums)
