I had the pleasure of attending a double billing, Van Morrison/Dylan, in Boston about 10/15 years ago. The high point of the night was the sound of a single note played on a harmonica by Van Morrison. It had the positioning and placement and tone and volume and duration and color and sound and vision that made the price of admission worthwhile. I can't explain it. "It stoned me to my soul......"
I have seen Dylan many times live. Him live is nothing like his albums though. I saw the Rolling Thunder Tour four times.
