The Robischon Gallery is so big that it's easy for co-directors Jim Robischon and Jennifer Doran to mount large and impressive group shows in which each artist is given his or her own spacious berth. And not incidentally, they also have the curatorial talent to be ambitious. That was surely the case with Out of Line, in which an overarching, unified vision of contemporary abstraction was achieved through the sum of its individual artist parts, including mostly conceptual abstract pieces by Jason Karolak, Wendi Harford, Ted Larsen, Derrick Velasquez, Kate Petley, Annica Cuppetelli + Cristobal Mendoza, and Bernar Venet. The results were spectacular, and by mixing up nationally known artists with prominent locals, Robischon and Doran showed how good the hometown team really is.
