"Trestle," 4-channel sound installation, Northern Pacific Railyard, Brainerd, MN. Sound excerpt.
Artist Pete Driessen commissioned two sound works to accompany the monumental site specific
installations, "Trestle" and "Trestle Worker," reflecting the architectural spatiality of the former rail yard spaces. The composition for the longer "Trestle" sculpture is meant to be physically supportive and sensually immersive, while promoting the affective experience of the viewer within the installation. "Trestle" comprises of two parts. Part 1 uses sounds sourced from within the architectural space itself as starting material. These sounds are then processed in the computer to create a piece that captures the natural resonances found in the exhibition space. Part 2 focuses on a 60Hz electrical hum present in the space from a power generator. Each speaker plays tones that emphasize harmonics of the existing 60Hz tone.
