If anyone is in Southern California, the 10th annual (and possibly final) Soundwalk sound art exhibition in Long Beach will be this Saturday from 6:00-10:00 pm.
My piece for this year's event, titled Solipse, was created entirely with PD and is described thusly:
"The listener hears a unique sound. The sound is interesting, but the listener is incapable of describing it to others. Attempts to share the sound cause it to abruptly change."
