A major American artist working between minimal art and what has been called Anti-form, Keith Sonnier has been working since the late 1960s on a redefinition of sculpture. He uses color and light in objects and installations where fluorescent tubes, neon, or argon - his favorite materials - allow him to draw in color in space. Colored plans, glass surfaces, gauzes, wooden elements, film projections ... His sculptures play with reflections, opacity, transparency, the transformation by the light of materials and their intrinsic color. Inspired by his youth in Louisiana as much as by his travels, his sculptures are often hybridizations, between traditional forms and contemporary elements, between geometric shapes and a design affirming a baroque dimension, using both the floor and the wall.
