Co-ops typically present solos by their members, featuring group shows only when a time slot accidentally opens up. Such an unexpected opportunity presented itself last spring, and Edge member Mark Brasuell came up with Directions in Abstraction off the top of his head. He included his own work and that of four others -- Dale Chisman, Clark Richert, Bruce Price and Karen McClanahan -- to explore new approaches in abstraction. Brasuell and Chisman focused on abstract expressionism while Richert looked at geometric abstraction, and his former students, Price and McClanahan, did post-minimalism. Though each person was represented by a single piece, it was a good start to a survey of the best abstraction being done here.
