Query: A Musical/Spiritual Journey That Remains Valid Today

Totally captivating on vinyl in 1969. Refreshing and enlightening on cassette in 1984 while still holding some "Future Shock". Still a valid and commanding work in 1999 remastered on CD. Required listening in all of my music libraries that include music from The Dillards to Angelique Kidjo. Unarguably, the best of the Moody Blues!
