Despite the limited budget, the friendship between Aldo Lado and composer Ennio Morricone made this collaboration possible; nonetheless, only a 45rpm 7" was released at the time, containing the songs "Coincidenze" and a 'medley' version of the theme track with the train wheels rattling on the tracks in the background, while the song "A Flower's All You Need", sung by Demis Roussos of Aphrodite's Child, was included in a rare Japanese single. All these tracks can be found in this exclusive edition of Morricone's soundtrack, together with the various other versions of the film's main theme, characterized by a middle section filled with tension, pronounced rhythmic patterns and echoes of the legendary theme of “Investigation of a Citizen Above Suspicion". The notes of "Coincidenze" are just as worthy of the best Italian police movies, while the "Solitudine" theme adds sadness and melancholy notes to the mix. Franco De Gemini's harmonica also reminds us that this kind of films are nothing else than westerns set in modern times and contexts.
Yet another exceptional work by the Maestro, released for the first time as a yellow coloured vinyl enclosed in a gatefold cover!
