Hades was part of the music conceived as an aural art piece to accompany the release party of The Residents toy figures recently designed by Steve Cerio. The original music was conceived to utilize two DVD players that were programmed to randomly play abstract bits of music. They would play 5.1 surround audio and each would play different things. The project (which required 12 speakers placed in a circle around the gallery) was entitled Chaos is not just a theory. In Greek mythology, Hades was a child of Chaos.
As these kinds of things go, it never quite worked out. The gallery never agreed to provide the sound system and some people felt it would be unpleasant for attending guests (correct) so by the time the toy release actually happened (there were several lengthy delays) The Residents had lost interest and had moved into other projects which did not allow them to even attend the toy release opening.
However, Homer Flynn, Leigh Barbier, and Steve Cerio did attend and showed non-Residents art work. The cover art is from the work shown by Mr. Flynn.
Hades was adapted by The Residents from part of the music written for Chaos is not just a theory especially for this release. 2008.
