Never seen the film, nor have I heard of it. It's hard for me to pass an Ennio Morricone on vinyl when I see it used. Once you put it on, it's clearly Morricone. Which means, one can tell it a distinctive sound of how he uses piano, wordless vocals, and horns used as sound instruments. I'm amazed at the range of his abilities to make music. Not quite avant-garde, or musique concrete, but traces of that sound is on this album.
Oddly, this soundtrack hasn't been reissued (as far as I know). It's an incredible piece of work. I find it odd that listening to it, I think of Brian Wilson era "Smile." Wilson's sensibility in arrangements (especially in that time period of recording "Smile) matches the spirit of "Quando L' Amore é Sensualita. Well, clearly the Morricone sound is more sinister.
The first cut on side two "Luce Chiara Per Vergine "Curve Oscure," is a combination of pop, but in a very strange version of it. This piece of music can easily fit into a current Scott Walker album. I listen to this vinyl gem, and I can't imagine how he does it? To call him a genius is somehow an underestimate of his creative worth. Anyone who has even the slightest interest in composition or arranging needs to hear this album.
