In L.A., they guy was Steve Mann. To this day, the most astounding and creative finger-pick guitarist I've ever seen/heard (and a decent singer). His legend is certainly secure, but he never attained wide recognition. He made two albums, both rather poorly recorded, but if you can get your hands on them, they're gold! Also, I went to college with a terrific folk singer named Bill Vanaver. A multi-instrumentalist and really good singer, he certainly fashioned himself after Pete Seeger. He made a few albums, but never "found fame", and last I heard he operated a "folk troupe" of singers and dancers in New York. Both of the above are fabulously talented, but the masses missed them.
