The Moody Blues - the night nights in white satin, 1967

"Days of Future Passed is the second album and first concept album by English progressive rock band the Moody Blues, released in November 1967 by Deram Records. The album represents a significant creative turning point for the band. The album is their first with guitarist and singer Justin Hayward in place of Denny Laine and bassist John Lodge in place of Clint Warwick. The album is also their first to feature longtime producer and collaborator Tony Clarke and the first to feature keyboardist Mike Pinder on Mellotron. These changes, combined with a shift away from R&B covers toward original compositions and a thematic concept, helped define the band's sound for the next several albums and earned the group new critical and commercial success."
