If the Moody Blues' most brazen, brave, and bold November 1967 mixture of conceptual rock and broad classical arrangements known as Days of Future Passed both saved their career and opened newer doors of sonic perception for them (and us) to walk through, then their mind-expanding July 1968 follow-up, In Search of the Lost Chord, truly cemented their position as purveyors of some of the headiest of mixes to essentially usher in a new era of progressive music. Indeed, the magnificent Moodies' late-'60s and early-'70s stereo mixes are often credited with helping to sell the true advantages the then-burgeoning FM format had over AM radio in the United States.
