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.

number phase: 12 – 19 / 20 – 90
William "Bilwa" Costa

number phase: 12 – 19 / 20 – 90 is an electroacoustic composition for live voices, recorded voices, and sine tones. Based on a personal observation of counting, in several East Asian languages, the concept is to utilize listening perception as a means of composition, incorporating phasing, oscillation, binaural beating, and repetition. This composition combines real-time and recorded counting in Mandarin, Cantonese, Hakka, Taiwanese, Korean, and Japanese, with a series of eight sine tones. This combination of voices and tones, having varying effects on each other, come together as a single sound palette.

Performed by:
Wei Wei Leung, Wei Ze, and Kae San (voice)
Kamil Korolczuk (klangregie)
William "Bilwa" Costa (sine tones, playback)

Thanks to Inwha Paik, whose recorded voice is heard counting in Korean,
and to Ayaha Tokusa whose voice is heard on the album version counting in Japanese.

The premiere of number phase: 12 – 19 / 20 – 90 is made possible by the generous support of the Musikfonds e.V.

number phase: 12–19/20–90

stadt_wehlen_bridges

un/natural fields:once removed is a composition which addresses time and place, both linear and non-linear. It utilizes the urban landscape of Berlin, specifically the Ring Bahn, as a source of composition.

The city of Stadt Wehlen, as well as its surrounding nature, is used as a source for cultivating sounds. Sounds recorded in Stadt Weheln and its nature, which are recorded by participants, are “over-dubbed” (played back on Ring Bahn and re-recorded) in Berlin. These combined sounds were used as a sound palette for the composition.
un/natural fields:once removed was performed live as an acousmatic performance, in an attic, using a four loud speaker installation and two hand held speakers
