For one year beginning in June 2000, [The User] will animate an ongoing audio exploration of Montréal's Silo #5 grain elevator. SILOPHONE combines sound, architecture, and new communications technologies to transform this landmark of Montreal's industrial cityscape. The SILOPHONE instrument blurs the boundaries between music, architecture and net art. Using a combination of communication technologies including internet, telephone and radio, sounds from around the world will be drawn into the Silo. Sounds arriving at the site will be broadcast into the vast concrete grain storage chambers inside the building. Reverberated, transformed and transfigured by the remarkable acoustics of the structure, the sounds will be captured by microphones and rebroadcast back outside the building. Throughout the year, a series of artists will be invited to propose musical interpretations with the SILOPHONE.
