There was a lot of stuff going on at the time.
People forget that the first Moon landing, Woodstock, Kennedy leaving Mary Jo to drown in a river, and the Manson Family murders in LA happened in the course of a few weeks. Among other things.
I seem to recall the music rights to the concert were tied up for decades. Probably still fighting over it. Same with “Concert for Bangladesh”.
Anytime something is “Free” it gets all kinds of f@&!ed Up. Hippies never really learned that.
The music was pretty spotty, performance wise. It looks to me, or listens to me, that Santana, Joe Cocker and a very few others did well, sonically speaking.
and on the last day of Woodstock...that night, Hurricane Camille destroyed the Mississippi Coast and changed forever the way the U.S. looked at hurricanes....
Hendrix was not “spotty”.
