I’ve recently stumbled onto some Ennio Morricone scores that I hadn’t heard before, which may be an experience I’ll have again and again for the rest of my life (the man has 521 listed credits on IMDB alone). And it came to me, who the hell was the Whistler? The man who actually did the whistling for The Good, The Bad, and the Ugly.
Turns out it was a childhood friend of Morricone’s, Alessandro Alessandroni, a fellow composer and the guitar player as well as whistler on most of Morricone’s immortal songs. Here’s a link and another - the man’s ability and tunes are haunting, beautiful, a truly unique skill set.
