built from recordings of architectural spaces resonating, being sounded by orchestras and ensembles playing re-scored sections of adagios - a few seconds re-scored as durational performances 

recorded using JrF c-series contact microphones and adapted geophones 
on and around each location 

this technique of using buildings as filters for sound performances, and in and of themselves, is one that I have developed over the past decade or so and stems from my interest in sounds not normally audible to us, and on how structures affect our sonic experience. 

first realisation is available on this release:
