Spring Biography (Wikipedia)
Spring were a Leicester-based British progressive rock band.
They released only one album in their career, a self-titled LP in 1971. Spring's music is notable for the use of the mellotron with three of its five members credited with playing that instrument on the album. Songs for a second album were recorded but not released at the time. They were later released on CD together with some demos as Untitled 2, as a bonus CD on the Esoteric CD release of 2015, and as a bootleg vinyl album Spring 2 (with Roger Dean cover). Three of the tracks were used as bonus on the single CD edition of the first album.
