Well, Rick, I might qualify if coming at it from all directions at once counts. I went from Lawrence Welk's bouncing ball and Andy Williams to the PP&M and Dylan school of folk, then to Chad Mitchell Trio and Tom Lehrer (Anyone remember TW3?), and then to Seagall/Schwall (then called Cat Mother and the All Night Blues Boys) whose stuff I heard at the Ann Arbor Blues festival along with Lightnin Hopkins, if memory serves me. (Like Big Mick said, if you can remember the '60s you weren't there).
And after listening to some of these blues guys, and Taj Mahal, and Sonny and Brownie, I found Fresh Cream and Greatful Dead (Workingman's Dead and American Beauty) and liked them for having their roots showing.
Course at the same time I was listening to Beatles and Rolling Stones, Doors, Mothers of Invention, Leonard Cohen, Simon and Garfunkle, Michael Cooney, Sara Grey, Gordon Bok (I found his first record in the store in 1965, has a picture of him on the cover trying to look older, smoking a pipe and gazing out to sea. I b'lieve it was produced by Paul Stookey.)
(and then there was the classical stuff I was listening to). Does this meet your specs?
Blessings,
Barbara
