Having just heard Joan Baez in a recent concert, I think she has abandoned folk. Her set still includes "folk" material---some Guthrie, et al; but her backup is very rock. This doesn't negate her impact on the folk scene, nor does it lessen her legacy. It just seems a shame that she has changed her style. Judy, too, has moved to a much less traditional sound for backup. I guess the old "girl and her guitar" way of presenting folk material has not been lucrative enough.
