Philip Glass wrote the soundtrack for the new movie, The Fog of War. In it, Errol Morris interviews Robert McNamara about his experiences during World War II, as a Ford executive, and as the Secretary of Defense during the Viet Nam war.
The music has considerable variety for a documentary and was divided into many, not necessarily related, sections. Timbre was particularly varied, with use of flute, percussion etc. over string accompaniment. Some of the music is reminiscent of Koyaanisqatsi, where anonymous people in public spaces are shown to fast-paced music.
Some of the Viet Nam-related segments had an atmospheric, non-rhythmic, even psychedelic feel. In the closing credits, John Kusiak was also credited with providing music, presumably these parts. The film also incluced a segment of an old CBS Reports television program (was that Morley Safer?) that used Copland's Appalachian Spring as the theme.
All in all, the music, on first listen, sounds both reminiscent of Glass but also more sophisticated, at least in color. The cinematography and well-chosen historical film clips were memorable. Separated from the film, the soundtrack may turn out to lack coherency but with it, "Philip Glass Meets the History Channel" was compelling.
Amazon has sample streams as well as MP3 downloads.
Sufjan Stevens, a pop musician who released an album touting the merits of the state of Michigan hates soundtracks, including this one.
