Two Trash Can Recordings (He didn’t like collage). Sound Observation #6

live diffusion of four channel digital audio (2010)

"Sound Observations" is a series of electro-acoustic works – live performances and real time sound installations – that utilize narrow band-pass filters to observe the spectra of live or recorded soundscapes.

For "Two Trash Can Recordings (He didn’t like collage)", two recordings were made by holding a microphone into trash cans, thereby observing the resonant frequencies of their interiors as stimulated by the surrounding soundscapes. The two trash cans were located in New York City on 55th Street and 7th Avenue, and on the 86th floor observation deck of the Empire State Building.

Throughout the piece, both recordings are played together, though they never mix. In the first movement ("horizontal"), excerpts from the two recordings are introduced successively, then simultaneously. The simultaneous recordings are strictly filtered such that the two frequency bands move toward each other without meeting. In the second movement ("vertical"), the two recordings retain their full vertical frequency range, but rapidly alternate until our sluggish perception blends what actually remains separate.

The duration is approx. 5’40”. Audio recordings by Gerhard Schultz and Volker Straebel, audio programming by Fabian Brinkmann. First performed at Experimental Intermedia, New York, on December 19, 2010.
