The Ambient Temple of Imagination is an open collective dedicated to activating the world's imagination through experimentation.

Part ambient-trance group, part holistic listening-music healers, ATOI's Mystery School project was founded in 1992 by Richard Sun and Seofon in San Francisco as they pioneered chill-out sound environments for raves around the area. With introspective chill spaces, ritual performance art, and spoken-word poetry, ATOI focused on the public ceremonial exploration of magick and sound.
