Most documentaries have garbage audio with music that is irrelevant or to loud when people are talking. The audio quality of this film is honestly refreshing. There are times when people are speaking and the tone of their narrative is being supported by the mood of the music playing softly in the background. Other times the music is the only audio and it embodies the images the viewer is seeing and expands the feeling they create. Seriously great audio work that is rarely seen in documentary films these days.
