Opening sequence music
OK, we all know this score has been made by the "always(well, almost)-excellent" John Williams, but, from my point of view, the opening sequence track reminded me a similar music by Tangerine Dream from their album "Stratosfear" - circa 1976, same year of this movie...
The strangest thing is that particular music doesn't "sound" from the usual vein of the compositor. Silly me, maybe, but sounded weird to my ears.
Just to share from thoughts.
