I've ever witnessed are now listed (not exactly in order of importance) at:
"1. Altamont -December 1969, with my dog Gypsy-Rose in tow; Hells Angels whoop ass the crowd to music from Santana, Jefferson Airplane, Flying Burrito Brothers, Crosby, Stills & Nash, & Rolling Stones. Saw Mick blind-sidedly cold-cocked up close then carried backstage unconscious on stretcher as he attempted to go thru crowd just after arriving. Quite an entrance.
2. Beach Boys at the Hemet Armory -Southern California, very early 1963 before a crowd of 50 or so. Spent break with them in parking lot as the Wilsons & Love drank beer.
3. Bob Marley, Peter Tosh, Bunny Wailer, Joe Higgs & The Wailers at The Matrix -San Francisco, October 1973. Had never heard of any of these guys until the curtain opened.
4. Tim Buckley at The Troubadour -several times, Los Angeles, Fall 1967-Spring 1968 along with Nina Simone, Richie Havens, Hedge & Donna..."
Hendrix, Nusrat, Dube, etc. with many more, several still to be listed.
