The soundtrack to Sam Peckinpah's film is split between instrumentals and full-fledged songs, including the repeated "Billy." This essentially is mood music, and it's quite effective on that level, but "Knockin' on Heaven's Door" — his greatest song since "John Wesley Harding" — gives the album some weight and is the main reason for purchasing the album. While the rest of the album isn't just pleasant, it's effective, conjuring images of the mythologized wild west that the film itself evokes, it still winds up being a lesser item in his catalog, despite the presence of "Knockin' on Heaven's Door."
