The PARTCH Ensemble players deserve much credit for performing on the Partch period instruments. These are only accessible for practice a few weeks prior to the show, have unique layouts and are tuned to many exotic pitches. Just reading the part scores is also very demanding. The difficulties are formidable, but the playing in this concert was smooth enough that the listener’s ear soon adapts to the alternate tuning and becomes comfortably immersed the Partch sound world.
