In 1969, with Patrick Lucchini and Claude Rychner, Armleder founded the
Groupe Ecart in Geneva, from which stemmed the Galerie Ecart and its associated performance group and publications. The
Groupe Ecart was particularly important in Europe during the 1970s and 1980s, not only through its activity as an independent publishing house, but also because it introduced in Switzerland—and sometimes in Europe—a large number of notable artists, including
Joseph Beuys and
Andy Warhol. Armleder was later associated with the
Neo-Geo artistic movement in the 1980s. Armleder frequently examines the context in which art is displayed and views the exhibition as a medium in its own right. Since the 1990s, he has created installations, paintings, wall paintings, sculptures and what he calls
Furniture Sculptures—installations that usually juxtapose furniture with monochrome or abstract paintings, either literally on the furniture or a canvas hanging nearby. His work has varied greatly in form, and has, since the beginning, used chance as a method of producing the final forms that pieces take, much like
John Cage. He often uses a dense scenographic hanging style, putting individual works into proximity and creating installation-like exhibitions. ==Exhibitions==
