I tried to start a thread on the Baez and Carthy interview on world cafe, which nobody bit on. I was especially interested in Joan's comments on needing a voice coach as she got older -- realized she needed one, to save her voice, as well as deal with changes in her voice. it was a good interview.
I always liked Joan Baez, but the break in her young voice did give me pause, since as a singer, so much of my work involved the physical work to get in back of the break and connect it.
I do think Joan sings better now.
