Roman Signer, born in 1938 in Appenzell, who has exhibited at documenta 8 in Kassel (1987) and at the Venice Biennale (1999), is regarded as one of the most important contemporary artists in Europe. Although he is best known for his spectacular actions involving dynamite, transformation, explosions, and demolition represent only one aspect of Signer's art. Since the seventies, he has devoted much of his creative energy to a redefinition of sculpture, incorporating time, acceleration, and change into the sculptural process. His artistic ideas revolve around the relationships between sudden discharges of force and calm, order and chaos, and form in a seemingly formless environment. The catalogue provides an in-depth survey of Roman Signer's work as an artist from 1971 to the present. It includes an introduction by Michaela Unterdörfer and an essay by Gerhard Mack on the aspect of suddenness in Signer's art. The DVD-Video documents a performance in which Roman Signer guides a group of Harley-Davidson bikers through the exhibition. Exhibition schedule: Sammlung Hauser und Wirth, St. Gallen, May 11 - October 12, 2003
