Ennio Morricone
composed hundreds of original soundtracks for this style of low-budget thriller. The original soundtrack for this obscure Italian thriller from 1970 prominently features the voice of
Edda Dell'Orso
, who cropped up frequently in
Morricone
's work during this period. Additionally,
the Canori Moderni
vocal ensemble features heavily in the evocative soundtrack. Most striking is the manner in which the composer uses repetition in an almost
minimalist
fashion. The unusual orchestrations of his work, which would later become a signature of his soundtrack compositions, are strikingly evident here. ~ Skip Jansen
