T.S. Eliot said the bloody-minded playwright John Webster “saw the skull beneath the skin,†and here artist Richard Aldrich demonstrates a similar X-ray aptitude with canvas and its frame. Taking a cue from Arte Povera artist Lucio Fontana, Aldrich began with a painting that wasn’t quite working out, and then excised and excised until all that was left was this spare, spiritually ascetic result. Add a few paint-streaked wooden slats, and presto, it’s a sculpture.
