ARNULF RAINER

After 1954, Rainer's style evolved towards Destruction of Forms, with blackenings, overpaintings, and maskings of illustrations and photographs dominating his later work. He was close to the Vienna Actionism, featuring body art and painting under the influence of drugs. He painted extensively on the subject of Hiroshima such as it relates to the nuclear bombing of the Japanese city and the inherent political and physical fallout. From Wikipedia
