Phil Kline’s Unsilent Night is a free outdoor participatory sound sculpture of many individual parts, recorded on cassettes, CDs, and mp3s, and played through a roving swarm of boomboxes carried through city streets every December. People bring their own boomboxes (phones with Bluetooth speakers are fine, too!) and drift peacefully through a cloud of sound, which is different from every listener’s perspective. Since 1992, this 45-minute work has grown into a worldwide annual communal event that has become an essential part of many winter holiday celebrations. This is the first time for the event to take place in Memphis!
