Summer group shows are a dime a dozen, but Matthew Higgs (director of New York’s White Columns) has guest curated a fantastic show of contemporary abstract painting, sculpture and photography, with a particular focus on vernacular (aka “everyday”) materials. Standouts include a Josh Smith oil next to a Warhol oxidation painting, an N. Dash photo of a linty ball of cotton and textile sculptures by Judith Scott, Shinique Smith and Alexandra Bircken.
