Arthur Roger pioneered the Warehouse District and fine-arts scene when he opened in New Orleans some 30 years ago, tying the local community to the New York art world. Still blazing trails with shows that range from strongly regional to far-flung, the gallery represents Francis X. Pavy, Ida Kohlmeyer, Dawn DeDeaux, Dale Chihuly, and the stunning, brazen figurative photographs of the late George Dureau.
