Johannes Hammel’s three-part Jour Sombre. He employed home movies shot in the 1950s and ’60s, of trips into the mountains, hikes across a glacier, alpine huts and lakes. We see groups of people spread out across the alpine landscape, in the background the dazzling white of the sun’s bright reflection from a glacier. Binoculars are pointed upward. At the sky, or the sun? Then a bubble appears, filling the picture and virtually swallowing the landscape. There’s a glare, as if a ray of light reflected from the ice were burning directly into the camera lens or our retina. Other bubbles follow, and the entire scene begins to boil. Heinz Ditsch’s soundtrack encourages this unsettling scenario. In the next part a swimming woman is harassed by nicks and scratches covering large areas, and what was originally idyllic becomes fractured and furrowed like dried clods of dirt. The soundtrack provides fitting crackling and scraping.
