The Alexander Desplat soundtrack for the 2005 film Syriana. A few of these tracks remind me somewhat of Satie's Gymnopédies. This one below is the final track, and features some of Desplat's characteristic use of foundations at the lower range of human hearing. The deep thrum reminds one of the heartbeat that is still the oil by which this planet lives, or the faint sound, almost more a feeling, that one gets if walking near high voltage electrical pylons. This wistful track, like the wrap of some others of Desplat's soundtracks, makes subtle references to themes presented more assertively in earlier tracks.
