The earth never sleeps. The duo Semiconductor distils research data on earth movements and animates them in a five-channel installation. In a dark hall, visitors to the Sónar Barcelona 2016 festival are captivated by a huge, luminous band of ceaselessly morphing layers of colours and strange sounds, experiencing a cut through both landscape and time.

Geologically, layers of earth form over thousands of years. The processes are almost imperceptible to humans. A research project in a Spanish quarry reconstructs earth movements, models them and records them acoustically. Creaking, rumbling and trickling, the layers leave traces of sounds animated in an audiovisual five-channel installation by the duo Semiconductor.

“Imminent danger, fear, catastrophe,“ the Austrian-Jewish composer Arnold Schönberg wrote on top of his film score in 1930, to which – except in this collage, swaying like a battered boxer between austere reading document, black film abysses and roaring tempests of images – no film was ever made. Schönberg’s letters articulate the forebodings of the disaster the National Socialists were to bring upon the Jews, describe anti-Semitism that was becoming systematic, marginalization and defamation. Inserted in between, as a look back and forward at historical continuities: bombers approaching Vietnam, the shot Paris Communards in coffins arranged like letter cases.

A very short film, infinitely sad and at the same time mischievous and playful. The opening credits tell us the devastating news: The filmmaker’s son was killed in an accident and left behind an unfinished flip book. The father resumes work on it and continues drawing the superhero tale, creating an animated film between deep mourning and carefree children’s logic. Capturing the proximity of happiness and loss in the most succinct form.

Walter Krüttner is considered the only satirist among the signatories of the Oberhausen Manifesto, which was announced at the West German Short Film Festival in 1962. His film begins like those that the Oberhausen group wanted to put a stop to: with ländler music and a quote by regional poet Ganghofer. “Lord, the ones you love you let fall into this land.” Krüttner observes the tourist hustle and bustle at Obersalzberg: tour guides leading Führer travellers through the Nazi buildings. And Krüttner counts the profits West German authorities make by this. He himself profited by winning the “Silberne Lorbeer” (Silver Laurel) of Deutscher Fernsehfunk (German Television Broadcasting), awarded at the International Leipzig Documentary and Short Film Week 1963.

A male voice, accompanied by the eponymous instrumental piece by Reinhard Lakomy, comments on photographic and material evidence of the events on the grounds of the Langenstein-Zwieberge subcamp. The audiovisual tour concludes with a visit by an FDJ (Free German Youth) group who lay down wreaths at the memorial site built in 1949. The speaker unequivocally classes this ritual of remembrance as part of the raison d’état.

Thoughts, sometimes just numbers, reach us from offscreen almost like music, like a mantra or a prayer. What we see are circular fragments from familiar spaces: a mirror, a magnifying glass. A day like any other day: without medication, or perhaps better with? A film like the investigation of an uncertainty principle: do we really see better with a magnifying glass? A face scratched out of the family album: the gap is draped with flowers and cut-out pictures of clothes and finally filled again by a drawing.
