Sadisfaction is the first album by Gregorian.Originally, Gregorian was conceived as a more pop-oriented group in the vein of Enigma. Under this concept, they recorded this album, with lead vocals provided by The Sisters of Oz: Susana Espelleta (Frank Peterson's wife at the time) and Birgit Freud. However, this was the only album in that style, leading to the Masters of Chant albums.
