I saw a documentary on JH a few years ago. It seems that he prefers playing with a band these days, and never records alone anymore, but that economics require that he tour as a solo act.

When I first heard John Hammond Jr, way back in the early 60s, I really didn't "get it." His style was a little too raw for me to comprehend at that time.

It didn't take too long for me to come around and learn to appreciate the real, down-home blues, and Mr Hammond the Younger certainly had much to do with my education.
