excerpt of live performance as part of 

fields
An evening of three, solo, sound performances; each incorporating or addressing field recordings and/or other forms of “fields”.
Echo Bücher, Berlin, DE

William "Bilwa" Costa / un/natural fields
un/natural fields is a project that utilizes un/natural field recordings, man-made, digital, analogue, and mechanical sounds, as well as many other incidental sounds, which make up a city's soundscape on metros and other indoor and outside public spaces. He has recorded sounds in various cities including: Istanbul, Mexico City, Shanghai, Beijing, Tokyo, NY, Berlin, Vienna, Prague, Riga, etc. In addition to recording, he does “overdubs” in which he plays back these recordings in other locations, creating new recordings which combine the unique qualities of two or more spaces/situations.

Bilwa combines these recordings with electro-magnetic mics and sine-tones to create experimental music scores which employ techniques associated with Musique Concrète, electronic music, and sound phenomena research; including: phasing, oscillation, binaural beating, cancellation, etc.
