"The Hum", or even "Taos Hum", refers to a low-frequency humming noise that is perceived by some people anywhere on Earth since the 1950s. Its unknown origin is the basis for numerous speculations about its cause.
The video THE HUM uses this signal, as well as others of unknown origin (audio files found on the Internet) for the basis of the soundtrack.
The imagery was built from long-exposure photographies of nocturnal light sources.
Both tracks are finally brought together into a cacophony of the unknown.
