Roman Signer has had many trades. He's worked in a pressure cooker factory, as a draftsman, a security guard, forklift truck driver, a water measurement assistant and in a polyester factory. It wasn't until 1972 that he saved up enough money to get a studio and start making art. From this biographical account, it's hard not to see how Singer's instruments have developed directly from his life experiences. Since 1973 Roman Signer has been in over 50 one-man exhibits and around 100 joint exhibitions. For the past few years his artistic sucesses have enabled him to do without part-time jobs. Signer's Suitcase is a kind of road movie across Europe - from the Swiss Alps to eastern Poland, from Stromboli to Iceland. Immersing yourself, letting yourself be infected, then travelling on. With his deadpan gags, Signer gives a humorous twist to the concept of cause and effect and to the traditional scientific method of experimentation and discovery, taking on the self-evidence of scientific logic as an artistic challenge. Filmmaker Peter Liechti's improvisational response frames Signer's visual humour with equally dry relish. A wonderfully diverting road trip, with Roman Signer leading the way.
