Pure plasticity — the
aesthetic «truth,» as it were — was expressed, if in different formal
terms from those of Cubism, in the abstract expressionism of Wassily Kandinsky, the leader of Der Blaue Reiter («The Blue Rider») artists in Munich, Germany, in Kazimir Malevich's Suprematism, in Russian Constructivism, and in the geometric abstraction of Piet Mondrian and Theo van Doesburg of the Dutch De Stijl group.
