Vinyl LP pressing. London-based psychedelic folk quartet Kaleidoscope formed as the Sidekicks in 1964, changing their name to the Key the following year. By the time they signed Fontana for the 1967 debut album Tangerine Dream, their choral pop harmonies were stronger and the musicianship more accomplished, the distinctly English folk undercurrents more pronounced. A favorite of Spaceman 3 and other connoisseurs of neglected psych, originals of this rare gem now change hands at extortionate prices and the work has aged like a vintage wine, the unjustly overlooked classic now rightly feted.
