D.A. Pennebaker's classic documentary, Monterey Pop, has been added to the National Film Registry. It was inducted to the 750-title strong collection with 25 other classics for 2018. Pennebaker filmed at the 1967 Monterey Pop Festival, which was founded by The Mamas and the Papas, along with Lou Adler and Bill Graham. It laid the blueprint for everything pop festivals would become afterwards, from Woodstock to Coachella.

“The National Film Registry turns 30 this year and for those three decades, we have been recognizing, celebrating and preserving this distinctive medium,” said Librarian of Congress Carla Hayden. “These cinematic treasures must be protected because they document our history, culture, hopes and dreams.”
