Guy,

That certain "sound" that Clarence got frailing his banjo was a truly other-worldly -- kind of a hollow overtone. I thought maybe it was based on his rapping right on the exact harmonic G-spot of the string. It sure was apparent and audible through the Mandel Hall P.A. system back in '61 ---- and that transferred beautifully onto the tapes radio station WFMT made of those festival's concerts. I think Folkways used some of those tapes for the LPs they made of Clarence, Doc and friends. ---- Either way, I can hear it in my mind's ear like it's happening right now.
