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. Crowd estimates for the festival have ranged from 25,000-90,000 people, who congregated in and around the festival grounds.[2][3][4] The fairgrounds’ enclosed performance arena, where the music took place, had an approved festival capacity of 7,000, but it was estimated that 8,500 jammed into it for Saturday night’s show.[5] Festival-goers who wanted to see the musical performances were required to have either an 'all-festival' ticket or a separate ticket for each of the five scheduled concert events they wanted to attend in the arena: Friday night, Saturday afternoon and night, and Sunday afternoon and night. Ticket prices varied by seating area, and ranged from $3 to $6.50 ($21–46, adjusted for inflation[6]).[7]
