Spring, also known as Spring Band, was a British progressive rock band that emerged in the early 1970s. The band, featuring a distinctive Mellotron sound, released only one self-titled album in 1971, which has since become a sought-after rarity among collectors. Notable band members included lead vocalist Pat Moran, who would later become a successful record producer. While their career was brief, Spring's unique fusion of progressive and melodic rock has secured them a significant place in the history of British rock music.
