“Sound Cast of Matanuska Glacier” (2015) is a sound artwork resulting from a decade of listening to and analyzing the Matanuska Glacier in south central Alaska, and engineering a “sound cast” of that glacier. The sound casting technique involves simultaneously recording many channels of audio across and inside the glacier in order to capture a sense of the total sonic signature of it. Air, water and ice microphones are spread across the glacier in a wide spatial array to measure vibrations through the ice and water in addition to the air. Reassembled later in a multichannel speaker array, this technique enables us to hear the glacier in a way that we cannot with our ears alone. The instrumental and electronic music uses a combination of sonification and free composition, putting science and imaginative music into dialog with the glacier as a dynamic musical instrument. The work can be performed as a concert piece with multichannel audio, or exhibited as a multichannel sound installation. As an installation, the musical piece is performed within the installation and then the glacier ecoacoustics remain in the gallery as multichannel sound diffusion.
