 During 1965 Castalia Foundation members collaborated with artists, including the media art collective USCO (The Company of US), to reproduce the LSD experience in improvised audio-visual psychedelic shows in Manhattan.The origins of the League for Spiritual Discovery can also be found in the Original Kleptonian Neo-American Church, whose clergy members administered sacraments in the form of psychedelic drugs.The church was founded in 1965 by Arthur Kleps, a participant in Leary's circle at Millbrook.
