Antiphon Trio features Michael Century (accordion), Chris Fisher-Lochhead (viola and pedal steel guitar), and Zach Layton (17-string bass) performing music built from an unusual instrumentation and composer Pauline Oliveros's Expanded Instrument System (EIS). The trio's acoustic sound is fed into this system of multiple delays and processing algorithms, producing an evolving, emergent timescape that rewards and requires deep listening.
