The whole series could not be a more brilliant showcase of the dedication behind "background" music of 1960's & 1970's Italian movies - that just because they are "scores" does NOT mean they can't be brilliant on their own as: easy listening, bossa nova, 60's spy themes, Class A jazz tracks, dance chill, or as fun lounge tracks.
