The Moody Blues were an English rock band formed in Birmingham in May 1964. The band initially consisted of drummer Graeme Edge, guitarist/vocalist Denny Laine, keyboardist/vocalist Mike Pinder, multi-instrumentalist/vocalist Ray Thomas, and bassist/vocalist Clint Warwick. Originally part of the British beat and R&B scene of the early–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 left the band by the end of 1966, being replaced by guitarist/vocalist Justin Hayward and bassist/vocalist John Lodge. They embraced the psychedelic rock movement of the late 1960s, with their second album, 1967's Days of Future Passed, being a fusion of rock with classical music 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".
