The Moody Blues' second album was also their first of what would be a succession of "concept" albums. Inspired by the Beatles' Sgt. Pepper and utilizing the London Festival Orchestra primarily for epic instrumental interludes between songs, Days of Future Passed moved the Birmingham band away from its early R&B roots (as displayed on its debut album with soon-departed future Wings member Denny Laine) into uncharted rock territory, making them the early pioneers of both classical and progressive rock. The concept of the 1968 release was very simple, tracing a day in the life from dawn to night, from awakening to sleep. The seven tracks spawned two hit singles--"Tuesday Afternoon" and "Nights in White Satin" (which hit No. 2 four years after the LP's original release) and a prog-rock cottage industry. --Bill Holdship
