Apryl Fool was a pioneering Japanese rock band formed in 1969, known for their unique blend of psychedelic, art, and progressive rock. Their sole self-titled album, released in September 1969, showcased a fusion of hard psych and blues-rock, featuring tracks like "The Lost Mother Land, Pt. 1" and a cover of Bob Dylan's "Pledging My Time." The band's lineup included vocalist Chu Kosaka, guitarist Eiji Kikuchi, keyboardist Hiro Yanagida, bassist Haruomi Hosono, and drummer Takashi Matsumoto. Despite their brief existence, Apryl Fool's innovative sound left a lasting impact on the Japanese rock scene, with members later contributing to influential groups such as Happy End and Yellow Magic Orchestra.
