If anyone is interested in Americana, and the evolution of music in America, the new PBS series "American Epic" has been excellent so far. I'm happy that Jack White (and Third Man Records) is so heavily involved, and already planning to release a series of LPs based on these long-forgotten artists and their music.

And if you enjoy this show, the radio shows below are also very good, the latter being more Vermont-focused.
