Amidst the 1950s world of Heinrich Böll’s fiction, a radio producer named Murke, exhausted by the banality of cutting and splicing broadcasts, would take home taped fragments of silence from the studio to contemplate in his own time. From Jan. 23-30 in Berlin, sound artist André Castro performs a similar exercise with this installation, channeling a collection of breaths, gasps and “collected silences” between the legible sounds on the radio into the space at Enblanco. Concocting a computer formula that feeds off of live broadcasts, Castro literally highlights what you often don’t hear by muting words and music and hooking up what remains to a light responsive system.

At the opening this Saturday, fellow sound alchemists Klaas Hübner, Rúben Patiño, Benjamin Altermatt and Nuno da Luz will further the subtle labor of making something out of nothing by crafting music out of these radiophonic fragments. Run through various devices, these bits of nothingness will expand, deflate, stretch and take on strange, unexpected contours.
