Deep Listening Band, an American musical ensemble founded in 1988 by Pauline Oliveros, Stuart Dempster, and Panaiotis. The group is named after Oliveros' concept of Deep Listening, which involves performing and recording in resonant spaces such as cathedrals and underground cisterns. Their first self-titled album was recorded at the Fort Worden Cistern in Port Townsend, WA, in October 1988. David Gamper joined the band in 1990, replacing Panaiotis. They released the album Troglodyte's Delight in 1990. Notable releases include collaborations with Ellen Fullman and her Long String Instrument on Suspended Music (1993), and a trope on John Cage's "4'33" titled Non-Stop Flight (1998). The band celebrated its 20th anniversary in 2008 with performances at Bard College and Roulette, NYC. Following David Gamper's death in 2011, the band released three albums featuring the trio Dempster, Gamper, and Oliveros, namely Octagonal Polyphony, Great Howl at Town Hall, and Needle Drop Jungle, all of which were released in 2012. In 2014, Deep Listening Band released Dunrobin Sonic Gems, marking the 26th anniversary of the seminal Fort Worden Cistern recording.
