Contributed by Sharon Butler / At the Walker Art Center in Minneapolis, curators Eric Crosby and Bartholomew Ryan have organized “Painter Painter,” an exhibition comprising work by fifteen artists, some of whom are working with painting materials in ways that are often labeled “painting” but may be more firmly rooted in  Minimalism and Process Art than with the formidable history of painting and abstraction. Considering the work presented in this show as well as the work selected for the deCordova Museum’s “Paint Things,” perhaps we aren’t experiencing an expansion of painting as the curators have proposed, but rather a return to handmade sculptural objects…that sometimes have paint on them or are hung on the wall.
