McMahon is a sculptor based in New York who creates impossibly suspended forms using plaster. He's not a stranger to Seattle, either. In 2014, his show at the now-closed Suyama Space in Belltown made waves when, during the closing reception, he dramatically destroyed his plaster sculpture of floor-to-ceiling curtains using a metal bar and gravity. Aperture, however, is dramatic insofar as the space it takes up. McMahon sprayed cast plaster over-inflated plastic molds, positioning them within a wooden structure that makes the plaster pillows appear to be bulging out of it. It measures 15 feet tall and looks believably plush. Sitting squarely in the middle of the space, the work pushes visitors to admire it while circling the outer edges of the gallery. What distinguishes this piece from his others is that you have a chance to view the interior of the structure. It's cavernous; I like the projected filled-ness of the plaster pillows from the outside contrasted with its hollow guts. by Jas Keimig
