During the 70's the Italian public television RAI used to broadcast disturbing and paranoid dramas, being the subject whether the bottom of the sea or the so-called "educational" movies. Obviously all these images needed a musical counterpart. Libraries more often. These ad hoc soundtracks were handled by shady characters, a number of composers on the border of classical avant-garde, electronic space age and even breezy Italian pop. Some of those names are pretty much familiar, Ennio Morricone, for example. Or even mythological too, as in the case of Piero Umiliani. But the brightest and maybe the most inspiring was Egisto Macchi. ESP was a four-part television series produced by Rai in 1973, directed by Daniele D'Anza, and aired from Sunday, May 27 1973 to Sunday, June 17, 1973.
