The exhibition "Surface & Substance" at the San Francisco Studio School Gallery displays work in a variety of media exploring the potentials, similarities and dissimilarities in two-dimensional art engaging a common substrate -- paper. Collage, drawing, printmaking and painting on paper by both East and West Coast artists are presented. The exhibition is a study in contrasts from the highly reductive work of John Zurier to Sandy Walker's large-scale brush drawings; Seiko Tachibana's modular wall installation to Hearne Pardee's collages. Work by Chuck O'Connor, Michalene Parker, Gina Werfel, Laura Harden and Lon Clark explore qualities of material, structure and visual language creating references to shared understanding and individual confrontations with issues related to contemporary aesthetics. The show offers a challenging and diverse view of physical materiality and visual metaphor.
