Conversation so far:
Did the Moody Blues take a hiatus during 1974-1977?
In the spring of 1974, after completing a vast world tour that culminated with a tour of Asia, The Moody Blues took an extended break.
Why did the Moody Blues take an extended break between 1974 and 1977?
The Moody Blues took an extended break because of band members feeling exhausted and overshadowed (this was said by Hayward in the final issue of Higher & Higher magazine 2006).
Did any of the Moody Blues go on to perform individually during their extended break?
Edge produced two albums with guitarist Adrian Gurvitz and his brother Paul Gurvitz, Kick Off Your Muddy Boots (1975) and Paradise Ballroom (1976); Hayward composed the acoustically textured Songwriter (1977).
