Post Traumatic System 024 ℗ & © 2008 A.J. Ptak

This live recording of theremin artist Anthony Ptak. Liner notes: Post Traumatic System [3:30] This computer/ theremin music work concentrates on difference frequencies as a carrier of information. We listen to the world as a system of associative indices. The acoustics are generated sine wave partials, synthetically generated interference phenomena. Sound is a virtual axis that occupies and transforms space. The heterophony of the score is navigation. The most anticipated 2008 performance at The Stone in East Village of New York City. Series curator Elliott Sharp. Recorded live in 8-bit mono March 25, 2008 at 10:00 p.m.. The Stone is at the corner of Avenue C and 2nd Street. Theremin antenna control of analog and digital oscillators, custom software. All sonic materials generated, performed, improvised and recorded by the composer. Thanks to Elliott Sharp. Dedicated to my late father. -A J Ptak
