Prolific sound artist Zimoun (previously here and here) has completed work on what may be his most ambitious project ever, a towering sound installation inside an abandoned toluene tank in Dottikon, Switzerland. The permanent installation uses 329 of the artist’s trademark prepared dc-motors and cotton balls that have been affixed to the inner tank walls, and relied on contributions from Hannes Zweifel Architecture, Davide Groppi, and many others. The result is a whirring, rhythmic soundscape that is completely camouflaged within an old factory. Via Zimoun’s artist statement: Using simple and functional components, Zimoun builds architecturally-minded platforms of sound. Exploring mechanical rhythm and flow in prepared systems, his installations incorporate commonplace industrial objects. In an obsessive display of simple and functional materials, these works articulate a tension between the orderly patterns of Modernism and the chaotic forces of life. Carrying an emotional depth, the acoustic hum of natural phenomena in Zimoun’s minimalist constructions effortlessly reverberates. Zimoun has completed several additional installations in the last few months, all of which can been seen on his website. Update: In case you’re wondering here’s a behind-the-scenes video of how it all came together.
