At the height of the Summer of Love powerhouses in pop music came together to hold the first Monterey Pop Music Festival, possibly the first pop music festival ever. D.A. Pennebaker was on hand to record the proceedings to be released as a film, though his footage was eventually released as three. We're talking all of them on this week's Lost in Criterion, including supplemental materials, as we explore the Complete Monterey Pop Festival box set containing Monterey Pop (1967), Jimi Plays Monterey (1986), and Shake! Otis at Monterey (1986).
