Oscar Wiggli is one of the leading Swiss artists of his generation. In almost sixty years of work, the artist has created an oeuvre of enormous technical and formal breadth that comprises subtle metal constructions as well as monolithic, monumental sculptures. Not only a sculptor, he is also one of the great graphic artists and photographers of the 20th century. He explores space and volume with acoustic strategies. He mixes sounds, tones and sound systems on computer to create virtual sounding entities which have attracted great attention in the avant-garde scene. This overview of works is the first joint exhibition put on by the Kunstmuseum Bern and the Zentrum Paul Klee.
