Since 2000, Staalplaat Soundsystem (Geert-Jan Hobijn) have been making sound artworks and performances, which are usually installed or performed in locations outside the museum – industrial settings, urban public spaces, even nature. Over fifteen years, Staalplaat Soundsystem has amassed a multidisciplinary oeuvre that is ephemeral and immaterial at the same time as it is physical and present. At TodaysArt 2015, Staalplaat Soundsystem (for this occasion consisting of Geert-Jan Hobijn, Radboud Mens and Bastiaan Maris) will create ‘Zeero’, a very large organ of four steel tubes with a length of 24 meters and a diameter of 1.2 meters. Staalplaat will use hot air balloon burners to create sound. The hot air allows for air movement in the tube, generating a very low tone.
