F. Gregorian (aka Frank Peterson) worked with Enigma on "Sadeness" as well as "The Voice and the Snake." The selected track, So Sad, sounds very much like Enigma's first album. It is taken from the album Sadisfaction. For more information on Gregorian, please vist The Frank Peterson Website maintained by Vaughan van dyk. This site is full of valuable information on the man behind Gregorian.
