Sound artist Ludwig Berger (based in the Palatinate Forest-North Vosges Biosphere Reserve, Germany) wants us to listen to our surroundings: to the insects, the trees and the mud volcanoes. In his latest film, Crying Glacier (2023, 14 min), film director Lutz Stautner (from Cologne, Germany) documented Berger. Like so many others, the Morteratsch glacier in the Swiss Alps is dying. Berger’s sound recordings of the creaking, cracking and rippling are his way of preserving sounds that could soon disappear from this world forever. The shortfilm can watched in the Op-Docs section of the New York Times.
