Portland-based sculptor-painter-taxidermist Peter Gronquist’s latest show “explores light as an added material to his paintings.” Some of these paintings—though that word strains under the weight of what Gronquist is actually doing—fall somewhere between a James Turrell space and a Dan Flavin installation. He’s interested in how light plays off the surface of his work, using Plexiglas (a type of acrylic) as part of each piece, adding LED lights to certain paintings and not to others. Additionally, Gronquist will also show A Visual History of the Invisible, a series that attempts to capture the shapes and constant presence of the wind. by Jas Keimig
