This is an excellent video about the three albums Dylan recorded in Nashville – Blonde on Blonde (1966), John Wesley Harding (1967) and Nashville Skyline (1969).
Blonde on Blonde is my favorite Dylan album. I don’t think the songs are better than on Highway 61 Revisited but the musicians are. The backing is much more subtle unlike the pounding on Highway 61 Revisited. John Wesley Harding was released during the same period that the Beatles and Stones (and others) succumbed to the excesses of psychedelia. It was out of step then but sure sounds better now than Their Satanic Majesties Request.
