The LTA collaborated with visual artist Gaël Grivet on his Talweg Vol.1 project. This sound installation, presented during the Radical Biotope exhibition at Ferme-Asile in Sion, presents a series of microscopic images of vinyl discs as well as a disc continuously broadcasting sounds recorded during a stay on the Aletsch glacier at the beginning of September 2017. The work thus exploits the formal and acoustic similarities between the glacial valley and the microgrooves of a vinyl record.

Visible from September 29 to December 10, 2017. For further information: http://www.ferme-asile.ch/ and https://matza.net/matza-aletsch-2017 .
