It's been eight-plus decades since the six arresting paintings in this exhibition have been shown together. Their emphatic use of color and geometric bent are hallmarks of Kazimir Malevich, the Russian avant-gardist who pioneered the form-centered Suprematist style as Europe was hurling itself into the absurdity of the first World War. Cubism and aerial photography — the designs and patterns of life writ large yet intricate — had a particularly deep imprint on Malevich's technique, and this exhibition zeroes in on his 1912-1922 timeline, when his oeuvre fades further from reality and into the eye-catching realms of the abstract.
