Pillars is very similar to Monomyth, differing in that it is performed over a concrete piece (download link above). Previous version of the concrete piece were proving to be to busy and convoluted to mesh well with the Kinect performance overlay. The solution was a thinner texture. Pillars employs important historical quotes relevant to the design of the piece.
Important to the emotion and overall concept of the piece were the lower frequencies. In the provided performance, a performer used a MIDI controller to create rhythmic disruptions in nearly inaudible subtones (though octaves were provided for recording purposes, as well as for making the piece accessible to all listeners).
A better performance would involve a form of gestural control over the subtones, rather than a MIDI controller.
