A series of sound installations derived from a single recording made in the empty spaces in which they are later presented, with no people present during the recording including the composer, filtered to isolate and amplify certain of the room's resonant frequencies, creating a series of drones which are the only sound materials used; no musical instruments are involved.

Ten sonically beautiful pieces derived from recordings made in empty spaces, transforming the sounds that leak in from the outside world using filters and amplification to find sonic resonance in those sounds and in the room's natural frequencies, like light filering into the space, each piece then played back in the same room at low volume as part of an installation presentation.
