The Monterey International Pop Music Festival was a three-day concert event held June 16 to June 18, 1967 at the Monterey County Fairgrounds in Monterey, California. Monterey was the first widely-promoted and heavily-attended rock festival, attracting an estimated 6,000 total attendees with to 10,000 people present at the event's peak at midnight on Sunday. It was notable as hosting the first major American appearances by Jimi Hendrix and The Who, as well as the first major public performances of Janis Joplin and Otis Redding. 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. It also became the template for future music festivals, notably the Woodstock Festival two years later.
