The Monterey International Pop Music Festival, a three-day concert event held June 16-18, 1967 at the Monterey County Fairgrounds in Monterey, California. It was the first widely promoted and heavily attended rock festival, attracting an estimated audience of 55,000 up to 90,000 people present by the event's peak at midnight on Sunday. The Monterey Pop Festival embodied the themes of California as a focal point for the counterculture and is generally regarded as one of the beginnings of the "Summer of Love" in 1967. Which also became the template for future music festivals, notably the Woodstock Festival two years later.
