Swiss artist Roman Signer (born 1938) has been a key figure in the Swiss art world for the last thirty years, and is one of the most important contemporary artists on the international scene. Following his most recent exhibitions, including a broad retrospective at the Bonnefantenmuseum in Maastricht and an exhibition of drawings at the Kunstmuseum Solothurn, Galerie Hauser & Wirth will be focusing on new installations and sculptures. Roman Signer is famous for making day-to-day objects do unusual things. In Dokumenta 8 (1987), for example, he catapulted thousands of sheets of paper into the air to create an ephemeral wall in the room for a brief, but all the more intense moment. For Skulptur. Projekte in Münster in 1997, he built a pipe into a walking stick and made it dance over a pond, drawing fleeting signatures on the mirror surface with a fine jet of water. Day-to-day objects such as umbrellas, tables, boots, containers, hats and bicycles are part of Signer´s working vocabulary. The artist also uses explosives to bring about rapid changes and transformations, and explores the natural elements water, air, fire and earth from an artistic point of view, using their innate power to mould and shape his works in plastic and visual form. Roman Signer has always described himself as a sculptor. Moving from the process-oriented concept of sculpture of the 1960s and 1970s, the artist sees the events he stages as plastic formations in space and time. In his work action and sculpture, dynamic and static moments are not mutually exclusive, but are part of the same structure. Each work could be divided into a before, an occurring event, and an after. His objects and installations contain traces pointing to prior processes of creation, which observers are forced to mentally reconstruct – or to anticipate possible changes which could arise from the power inscribed in the work. In this sense, Signer´s works operate on the boundary of the concrete and the imaginary.
