I once saw a scene from Silence of the Lambs without the post-sound work. It was significantly less scary, hardly even creepy... This got me thinking: in rather emotional movies, the score adds a great deal of emotional value that results -- at the very least -- in a knot in my throat.
Are there any films that have a film score in their standard version, but are also released without the score in a separate version? Perhaps for a study on the emotional effect of music in film?
