The Moody Blues were an English rock band formed in Birmingham in May 1964. The band initially consisted of Graeme Edge (drums), Denny Laine (guitar/vocals), Mike Pinder (keyboards/vocals), Ray Thomas (multi-instrumentalist/vocals) and Clint Warwick (bass/vocals). Originally part of the British beat and R&B scene of the early-to-mid-1960s, the band came to prominence with the UK No. 1 and US Top 10 single "Go Now" in late 1964/early 1965. Laine and Warwick both left the band in 1966, with Edge, Pinder and Thomas recruiting new members Justin Hayward (guitar/vocals) and John Lodge (bass/vocals). They embraced the psychedelic rock movement of the late 1960s, with their second album, Days of Future Passed (1967), a fusion of rock with classical music (performed with the London Festival Orchestra) that established the band as pioneers in the development of art rock and progressive rock. It has been described as a "landmark" and "one of the first successful concept albums".
The group released six more albums – In Search of the Lost Chord (1968), On the Threshold of a Dream, To Our Children's Children's Children (both 1969), A Question of Balance (1970), Every Good Boy Deserves Favour (1971) and Seventh Sojourn (1972) – and toured extensively until they went on hiatus in 1974.
