Though the NY-based writer doesn't mention it, the world premiere performances of the piece are taking place this week in Chicago.  It's a significant work, lengthy and difficult for the soloist, though not too bad for the orchestra.  I have no idea how Yo-Yo finds the time to learn these things on top of his myriad other commitments.

Because of its difficulty and logistical complexity (example: speakers around the hall to amplify real-time recorded tape loops from the soloist), I wonder whether the piece will enjoy frequent future performances.  Time will tell, but it's worth hearing for those who are near enough to do so.
