Even being majorly a country music fan, I've always liked Moody Blues from as far back as I can remember. Back many, many years ago I got really into recording music with really good equipment. My favorite was an Akia reel to reel that I played with for a long time.
The sound quality with good tape was fantastic, the frequency response was far more than the average human ear could hear, and with a good set of head phones it could take you to a different galaxy. One of my all-time favorites was "Moody Blues"
'In search of the lost chord'. Man, I could loop that and listen for days I think.
They and their productions/crews were light years ahead of most others in stereo and other effects of the day!!!
Best I can recall must have been in the early 60's?
