Arte informale is the Italian face of the postwar turn against rational abstraction. Named by the critic Michel Tapié in 1950 and parallel to tachisme and Abstract Expressionism, it privileged the artist's expressive impulse over premeditated form: gesture, matter, and sign became the basis of communication, and painting was approached as a spontaneous, experimental act. In Italy the movement took a strongly material turn - Burri's burnt and sewn sacking, Fontana's punctured canvases, Vedova's violent black-and-white cycles - while sharing the era's distrust of geometric purity. Italian critics later tied it to a broader European 'art of another kind', and its emphasis on raw matter fed directly into the experiments of Arte Povera a decade later.
