Impact of the festival
The Monterey International Pop Music Festival set precedents that all future rock concerts hoped to follow. For example, the festival's "bill was truly multi-cuntural and crossed all musical boundaries, mixing folk, blues, jazz, soul, R&B, rock, psychedelia, pop and classical genres" (http://stereolp.blogspot.com/2010/06/monterey-international-pop-festival.html). Not only did later concerts of the era follow this creative template, but even today major musical events try to mix genres in a way similar to that in Monterey. The festival also showed future event planners what must go into the production and running of such a massive concert. Both Woodstock and Altamont used the same organization of private security, medical staff, and drug-help volunteers that was modeled by Monterey (http://www.history.com/this-day-in-history/the-monterey-pop-festival-reaches-its-climax). For a concert to be heard by a crowd so large, a tremendously advanced sound system was required. The format of the powerful sound system was the design used at almost all the future festivals of the era. It ushered in a period of necessity for advanced sound engineering for large outdoor venues, as crowds that just kept growing needed to hear the music.

Monterey provided the opportunity for many artists of minority groups to present themselves as truly talented. Foreigners, blacks, and women all surprised the largely white audience and showed huge potential in the rock industry. The audience at Monterey, and the stereotypical rock concert audience become one that was far more tolerant of the strange or different, and as this audience expanded, its tolerance did too. Local police officers had been sent to the concert-grounds to keep control and had expected violence, but were astonished to see how well-behaved the viewers were. "The theme of the concert after all was peace and love" (http://temporalanthropology.blogspot.com/2013/03/the-first-monterey-international-pop.html). However, the impact of this may not have been entirely beneficial. At later, larger rock concerts, specifically Altamont, it was clear things got out of hand and violent. This may have been because law enforcement was expecting a much more peaceful audience, and when they realized this was not the case, the cops probably panicked and over-reacted (http://temporalanthropology.blogspot.com/2013/03/the-first-monterey-international-pop.html).
