While artistic experimentation has been a kind of tour-de-force, somewhere outside of painting, Waltemath has aggressively insisted that paint is still a frontier. It is left to wonder how obviously challenging her paintings and drawings appear to those who have no relationship with paint, given the balanced arrangement of lines and rectangles. Yet the aesthetic discoveries in her solo show Contingencies are a delight. Joan Waltemath’s methodology of experimentation renders a subtle but riveting combination of materials that engage both optics and kinetics.
