At Greg Kucera Gallery, wind is made solid by Katy Stone, whose acrylic-on-clear-plastic work you may remember from previous shows here: cascades of intense red or blue falling down layers of transparent Dura-Lar. She shows more work like this—in a softer, more monochrome palette: browns and blacks and nearly all-white pieces. But the most striking piece in this (her third) solo show at Greg Kucera is made not of Dura-Lar but of laser-cut steel. Nearly 11 feet wide by 14½ feet high, this construction, Edge of a World (wind), occupies the back gallery’s entire wall. Steel sweeps down in long, curved swathes. A few minimally detailed organic shapes—rough-edged branches with full blossoms—are caught at a 90-degree angle. In steel, Stone’s work is more solid and, somehow, more delicate as well. The edges are cut sharply, and instead of paint layered onto a clear ground, the edges pile up, creating a cleaner sculptural work, with strong shadows and a more defined physical presence. Greg Kucera Gallery, 212 Third Ave. S., 624-0770, www.gregkucera.com. Ends Feb. 9.
