I was wondering why they never repeated this festival despite all its success, I found out why from this article
“Unfortunately, the establishment was not prepared for all of the activities of the underground, which is understandable. After the festival, a proposal was passed
to prevent the State Fair Board from booking any event that would attract more than two thousand visitors without the permission of the city. In other words: no more Pop Festivals. (7)
The significance of this is that Monterey, like so many other festivals to come, never had the chance to be repeated. While this let festivals like Woodstock and Altamont shape the course of rock music, it denied a chance for future Monterey International Pop Festivals to have their influence.”
Discouraging, yes, but I still think it’s possible for things to change by now.
