Unsilent Night is composer Phil Kline's unique outdoor sound sculpture experience, offered for free annually in December. Participants bring their own boomboxes to join a roving swarm of music lovers through city streets. This participatory event features a composition split into parts played through individual boomboxes, creating a mesmerizing city-wide stereo system.

Since its inception in 1992, Unsilent Night has grown into a beloved holiday tradition, attracting crowds of up to 1,500 participants in New York City alone. The event has expanded to over 25 cities worldwide, including recent debuts in London, Denver, and Dallas, with upcoming performances scheduled in cities like Hong Kong, Oxford, and Charleston.
