In the 1980s, Lee Ufan developed two series, From Winds and With Winds, in which free and dynamic brushstrokes stir up a deeply empty space. While this painterly development appears expressive and full, it reflects Mr.Lee’s increasing interest in painting as a visible structure of invisible forces: his touch activates what he calls “the living composition of the empty spaces.” These compositions become distilled in Mr. Lee’s Correspondence series, which consist of a few black brushstrokes rhythmically placed on large white canvases.
