One of Moby Grape's earliest major onstage performances was the Mantra-Rock Dance — a musical event held on January 29, 1967 at the Avalon Ballroom by the San Francisco Hare Krishna temple. At the event Moby Grape performed along with the Bhaktivedanta Swami, fonder of the International Society for Krishna Consciousness, Beat poet Allen Ginsberg, and fellow rock bands Grateful Dead and Big Brother and the Holding Company donating proceeds to the temple. The group appeared at the Monterey Pop Festival on June 17, 1967. Due to legal and managerial disputes, the group was not included in the D.A. Pennebaker-produced film of the event, "Monterey Pop". Moby Grape's Monterey recordings and film remain unreleased, allegedly because Matthew Katz demanded one million dollars for the rights. According to Peter Lewis, " told Lou Adler they had to pay us a million bucks to film us at the Monterey Pop Festival. So instead of putting us on Saturday night right before Otis Redding, they wound up putting us on at sunset on Friday when there was nobody in the place."
