Release of An Oath is the fourth studio album by The Electric Prunes, released in 1968. Following the musical pattern of their Mass in F Minor, it is a rock music setting of a service intended to release a penitent from an oath "made under duress and in violation of his principles" (liner notes).
The album is subtitled "The Kol Nidre - a prayer of antiquity", and is often referred to simply as "The Kol Nidre". The Jewish Kol Nidre prayer, on which the first track is based, remains in current use as a central part of Jewish worship.
Despite the subtitle and popular name, the remaining tracks of the album are based on a mix of Christian and Jewishliturgies.
