The Moody Blues are a UK-based rock band best known for their smash hits "Nights in White Satin", "Question", and "Your Wildest Dreams" which have sold millions of copies around the world.
Initially a somewhat gritty British Invasion outfit who had scored a UK chart-topper with their second single "Go Now", the Moody Blues soon transformed into arguably the first progressive rock band at the popular level. Their 1967 album Days of Future Passed marked the beginning of a transformation that was enthusiastically greeted by record-buyers in the late 60s and early 70s. They were among the first to incorporate the Mellotron, which became a staple of experimental rock until it was eclipsed by the Moog synthesizer. Their intellectual approach and vocal harmony style suggested that rock and roll could go beyond the rough, street-level sound of its origins (a development which led to the term "rock" itself). The Moody Blues concocted a sonic approach that has been embraced by succeeding generations of fans.
During the 90's, they toured with a number of orchestras, beginning with the Red Rocks concert in 1992. Their final studio album, December, was released in 2003, followed by a double live album in 2005, Lovely To See You. To date they have sold over 50 million albums worldwide, produced numerous solo albums, and continue to tour.
