Leif Brush was a pioneering sound artist based in Duluth, Minnesota since the 1970s. His Terrain Instruments were just some of the audible sculptures that isolated and emphasised the sounds of otherwise natural phenomena.
In the forest outside Leif’s home in Duluth, he built a unique method of recording natural phenomena. The installation was called Terrain Instruments. Long ribbons of gleaming wire slashed overhead. Flat metal discs were suspended from thick cable. Both were connected with transducers running to a preamplifier, and then to an audio mixer.
“The inherent dynamics of the tree leaves to sound or the trunk and limbs to vibrate sound at frequencies commensurate with their mass and structure,” Brush disclosed in a self-made video production from 1984. “Each of these natural sources contribute very much as a natural Terrain Instrument.”
