The A-4P, or Air Purifying Plants Proliferation Project, is a collective initiative promoting environmental awareness within the Lamar Dodd School of Art and contemporary art studios beyond. The group, which is comprised of graduate students with concentrations in printmaking, painting and drawing, has organized “Preservationist,” an exhibition currently on view through Feb. 25. The interactive show features Minnesota-based assemblage sculptor David Hamlow and Alberta, Canada printmaker Sean Caulfield, whose art draws attention to the psychological and material byproducts of consumerism. Students, faculty and the artists will lead a public discussion related to “green” studio art practices and the potential in art to encourage sustainability. Beer tastings from Southern Brewing Company will follow.
