Which band closed the Monterey International Pop Festival in 1967?

The Mamas & the Papas closed the Monterey International Pop Festival in 1967.

The group performed on the festival’s final night, June 18, 1967. Their appearance provided a polished closing contrast to the event’s more exploratory performances by emerging and established rock, soul, and psychedelic artists.

The Monterey festival was held at the Monterey County Fairgrounds in California from June 16 to June 18, 1967. It became a landmark of the “Summer of Love,” helping introduce American audiences to performers such as Jimi Hendrix, Otis Redding, and Ravi Shankar.

The Who and Hendrix are frequently associated with the festival because both delivered especially dramatic sets there. They did not close the entire event, however: The Who appeared earlier on the final day, and Hendrix followed them before the closing performance by The Mamas & the Papas.
