Haus Konstruktiv is the first museum in Switzerland to devote a comprehensive solo exhibition to Otto Piene (b. 1928 in Bad Laasphe, d. 2014 in Berlin). A selection of works produced between 1955 and 2014 are being presented. Alongside early paintings influenced by abstract expressionism, there will be grid, smoke and fire paintings, light installations and air sculptures on display, in which the artist incorporated the elements light, fire and air to create a unique oeuvre that is still just as relevant today as it ever was.
