This document of a sound installation created in memory of the late Pauline Oliveros delivers the opposite of closure. As it proceeds, the lulling ambience is overtaken by the harsh slashes of what might be a violin, or a knife against rough leather for that matter. In retrospect — that is, upon subsequent listens — those string-like noises toward the end help reveal the source of the held tones at the track’s opening, the higher-pitch notes amid the general fog-horn drones. The violin is a constant presence, as it turns out, even though some time must pass before its presence becomes clear. The installation was created by the Vienna-born Mia Zabelka at the behest of the Austrian Cultural Forum New York (acfny.org). Pauline Oliveros, a maverick composer and sound theorist, was a practitioner of Deep Listening. So listen deep, put yourself inside Zabelka’s installation, and observe as her violin gains substance.
