During a lecture last week, I challenged the notion of creating the unplayable work. This is not new...consider Cage's Freeman Etudes.
Cage, himself thought the work to be unplayable. I participated in Irvine Arditti's morning sessions at Darmstadt in 2012 at the Orangerie and his performance of the etudes that evening in concert.
Herein lies the opportunity to define an ideated system of change.
