In 1968, Anger traveled to Britain, where he looked for potential new financiers for his work. In London, he involved himself with the social circle of Robert Fraser and his Indica Gallery in Mayfair, through which he met John Paul Getty, Jr., who would become a key patron. It was in this London counter-cultural scene that Anger decided to re-focus "Lucifer Rising" away from the Californian scene to embrace a more inter-continental approach. It was also in this circle that Anger met rock band The Rolling Stones, becoming friends with lead singer Mick Jagger and guitarist Keith Richards, as well as their respective girlfriends Marianne Faithfull and Anita Pallenberg. Jagger was intrigued by Anger, and realized that occultism had the potential to inspire a counterculture movement. Anger tried to convince Jagger to take on the role of Lucifer for the film, something that tempted the musician. Jagger composed music for the film using a newly acquired Moog synthesizer, with Anger later stating that "he was great. He did it for me in one night; we just climbed on the same wavelength." However, Jagger's composition would ultimately be used in "Invocation of My Demon Brother" rather than "Lucifer Rising". He also filmed some footage at a free Rolling Stones concert that was held in Hyde Park, which would subsequently be included in "Invocation of My Demon Brother". Anger put together that film using footage produced in San Francisco and London over the previous few years, and in August 1969 it was released on the underground film circuit in the U.S., where it attracted much attention and was screened as a midnight movie at the New York Elgin Theatre.
