Stuart Dempster created Underground Overlays From The Cistern Chapel in the same cistern where the legendary Deep Listening album was recorded. Reverberating with powerful, deep tones, this double LP is intended as a companion to the acclaimed Oliveros/Dempster/Panaiotis album Deep Listening. Underground Overlays From The Cistern Chapel is one of the deepest drone albums ever recorded. Nine trombones, didjeridu and Tibetan bells fill the massive two million gallon cistern with dense sonic reverberations that are both haunting and healing. Packaged in a heavy duty paper sleeve printed with metallic gold ink to match the Deep Listening design.
