On this project, released by the progressive San Francisco label New Albion, accordionist Pauline Oliveros has teamed up with trombonist Stuart Dempster and vocalist Panaiotis to produce a remarkable album of atmospheric space music. The recording took place inside a huge cistern at an army fort, an acoustic space characterized by tremendous reverberation. The unlikely instruments — primarily accordion, trombone, didjeridu, and voice — produce sustained tones that are subtly modulated by the extraordinary acoustics, making it often seem as if there were more instruments present, or as if this music has been electronically processed — neither of which is the case. All the music was improvised on site, with the musicians banging on metal pipes and found objects on the final track. The effect is remarkable, immersing the listener in a hypnotic field of shifting resonance, in a truly profound experience of deep listening. – AllMusic
