The electronic work makes use of dozens of boom boxes carried by volunteers, each playing a tape prepared by Kline. The result, wrote Josef Woodard in the Los Angeles Times, is "a dreamy fruitcake of parts, tranquil even through its anarchy."
In Philadelphia, the procession begins at 7:30pm at the Philadelphia Ethical Society in Rittenhouse Square. In New York, it starts at 7 p.m. at the arch in Washington Square park. Those who would like to participate should email Kline at firstname.lastname@example.org.
First performed in New York in 1992, Unsilent Night has expanded around the work. This year, it has already been heard in Cleveland, San Diego, and Middlesborough, England. It will travel to Vancouver and San Francisco on December 19 and 20.
