Zorn’s first appearance at the world renowned Venice Biennale was a spectacular one. Invited to perform The Hermetic Organ at the famed 17th century Palazzo Pisano, he was surprised to find two small antique organs opposite one another on the small stage of its intimate concert hall. His performance that day was one of the very best Offices of The Hermetic Organ—a wild, acoustic affair that takes full advantage of the rich reeds, flutes, and horns of these two outstanding instruments. Zorn ran back and forth between them, manipulating the stops with remarkable imagination and agility. There are difference tones and sonic cross talk here that sound absolutely electronic. A spectacular addition to one of Zorn’s very best CD series, now in its thirteenth volume.
