Unsilent Night is an original composition by Phil Kline, written specifically to be heard outdoors in the month of December. It takes the form of a street promenade in which the audience becomes the performer. Each participant gets one of four tracks of music, together all four tracks comprise Unsilent Night. The fact that the participants play different "parts" simultaneously helps create the special sound of the piece. Participants carry anything that amplifies music, and simultaneously start playing the music. They then walk a carefully chosen route through their city’s streets, creating a unique mobile sound sculpture which is different from every listener's perspective.
