Unlike most of the tracks offered here this excerpt from Deep Listening Band's album "The Ready Made Boomerang" uses not a single watt of electronic amplification, relying instead on the remarkable acoustics of Fort Worden's cistern: One notable feature of the park is the 2,000,000 gallon underground cistern, originally built to hold water for fire-fighting in the event that the fort was attacked and put to the torch. The cistern was drained in the 1950s when the fort was decommissioned, leaving an underground space more than 200 feet in diameter and 14 feet deep. This huge subterranean chamber has an acoustical
reverberation time of around 45 seconds, and once attracted the interest of various musicians and recording artists, among them
Pauline Oliveros, and
Stuart Dempster. (Wikipedia) Dempster is an emeritus professor at the University of Washington's School of Music and author of
