Mosset's artistic career began around 1965 in Paris, where he initially worked as an assistant to Jean Tinguely and Daniel Spoerri. He painted his first works with numbers, letters and dots on a white background. In 1966, together with Daniel Buren, Michel Parmentier and Niele Toroni, he founded the artists' group BMPT, named after their initials. With the intention of fundamentally questioning the predominant painting and starting from scratch, they organized four provocative community actions in which they broke with Abstract Expressionism and the École de Paris. The group disbanded in 1967. Mosset also became politically active during the 1968 movement. Between 1966 and 1974, Mosset produced around two hundred identical paintings: in an attempt to undermine the principle of authorship and create a painting that refers to nothing but itself, Mosset constantly painted black circles on white canvases. When these untitled circle pictures nevertheless become a kind of signature, he turns to horizontal and vertical, mostly two-colored stripe pictures, which lead him further to monochrome. In 1977 Mosset moved to New York, where he met important representatives of so-called Radical Painting and exhibited together with them. Until the mid-1980s, he was intensively engaged in color field painting, experimenting with various colors and formats, and always with a view to applying color without an individual style. In 1985 he returned to geometric abstraction and now also produced sculptural works.
Characteristic of Olivier Mosset's work is his penchant for cooperation, which is also evident in his exhibition at the Museum Haus Konstruktiv: In addition to current large-format monochromes, shaped canvases from the last two decades, and several early works, immaterial photographs can be seen that Madjid Hakimi, lighting engineer at the Paris Opera, developed in collaboration with Olivier Mosset.
