I can't believe I'm the first to mention Mary Travers.

I probably recognized women like Buffy and Joan as wonderful, serious artists, but Mary was something else, an absolute icon -- a charismatic stage presence; someone with admirable sentiments, a deep level of commitment, and the power to carry her message to the world at large; and (perhaps most importantly) *exactly* what a state-of-the-art hippie chick was supposed to look like.
