Geogaddi is the second studio album by Scottish electronic music duo Boards of Canada, released on 18 February 2002 by Warp Records. The album marks a darker sound from the group's debut album Music Has the Right to Children (1998). Characterized by heavily manipulated samples, analog textures and extensive use of subliminal messaging and backmasking, Geogaddi has been noted for its cryptic and mysterious sound design. The album's themes draw on numerology, paganism, the occult and religious cults.
