Every year a two-week workshop in painting - painting techniques, painting subjects, painting ideas - takes place "up the hill" in Idyllwild, as part of the Idyllwild Arts Summer Program. Conducted from its inception by Roland Reiss, who began the workshop after retiring as head of the art department at Claremont Graduate University, "Painting's Edge" brings visiting artists and critics from the Los Angeles area and other parts of the country together with enrollees whose own ideas and ambitions as painters keep the dialogue lively, collegial, and productive. For the past several years the Riverside Art Museum has hosted a show sampling work from "Painting's Edge" participants, visiting artists and enrollees alike, providing us a taste of the workshop's vital exchange of concepts and methods. Closer to sea level, the energy does not diminish a bit.
