Born in Chicago in 1955, Wool operates largely in black and white. His paintings tend to fall into two categories. His kinetic abstracts are alive but clouded with vicous swipes of gray, white and black, that give the impression of redaction, of erasing, of second thoughts, and that suggest both censorship and frustration. Though he's probably better know for his bold stencil works, with large block letters spelling vowel-less words like "TRBL." They were made years before the fine, dumb art of Twitter and texting shorthand, but feel like now, like Radiohead album art.
