I have noted herein, at Plastic Alto, that Charlie Musselwhite, the focal point and hopefully vocal pointman of my Earthwise event Sunday at Palo Alto JCC, played a show years ago at The Big Beat, also on San Antonio Road.
I found additional references and visual evidence of two other show:
a) at a Be-In type event — in the wake of the more well-known Grateful Dead concert — at El Camino Park — which maybe because it was so close to San Mateo County and Menlo Park that the convervative powers that be let it “Be”;
b) at PoppyCock, a club at the corner of High and Uni, where more recently there has been a Stanford book store and a bed place, I think. Poppycock was adjacent to another historic Palo Alto club, Top of The Tangent.
Also, and this appeals to me more than it might to Charlie Musselwhite blues fans who find their way here, one of the flyers also had a side bar for a Roscoe Mitchell show in East Palo Alto. I have a long article about the history of jazz here but maybe I can add some EPA info as it rolls in or rises to the surface.

There’s also a guy named Bernstein who produced some Sonny Terry shows at a warehouse downtown on Alma, and some shows at The Stanford Theatre.
