About halfway through the 20th century, the international postwar artists who called themselves the Zero Group tried to hit the reset button. As they saw it, modern art had been irretrievably damaged by two world wars. The only thing to do was start over.

“The Art of Zero: Heinz Mack, Otto Piene, Günther Uecker and Friends,” at the Neuberger Museum of Art, takes us back to that clean-slate moment. Its artworks soothe and pacify with flickering lights, gentle kinetic movements and endless variations on the white-on-white monochrome.
