I can chime in here....

My first one was May '69 five weeks before I got out of the military.
It was the Northern California Folk Rock Festival at Santa Clara County Fair Grounds.
Saw Hendrix and a few others I can't recall.

My second one was Lee Micheals and Albert King at Fillmore West in January 1970.

But...I lost my desire for large crowds and ear bleeding volumes several decades ago.

Have a great day...
