The gallery says that this show  "invites viewers… to challenge views about what art should be and how art should be expressed. Guest curator Jo Ann Rothschild selected work from abstract painters Emily BergerDavid FratkinColleen Randall and Elizabeth Yamin. Though each artist works abstractly, their works are vastly different. Emily Berger, for her part, notes that the  "paintings and drawings are based on a structure of repetitive and deliberate gesture that is intuitive but carefully considered."
