The music for the first film is harsher and more dissonant than that for the sequels, as is keeping with the tone of the film. As such, it bears more of a resemblance to Goldsmith's output of the 1960s and 1970s than it does most of his work in the 1980s. The first film's score does use electronics but is primarily orchestral while the sequel scores incorporate heavier use of electronics. The second film's score is the most popular, being that it is the most exciting. The music in the third film is an extension of the style used in the second, but with a few new themes. Both sequels feature new themes for Rambo that are based on elements found in the original "It's a Long Road" theme, which is also heard in its original form in each film as well.
