Arthur Roger helped develop the city’s fine-art scene when he opened in New Orleans more than 30 years ago, tying the local community to the New York art world and pioneering the Warehouse District. Still blazing trails, Roger schedules shows that range from strongly regional to far-flung work. The gallery represents Francis Pavy, Ida Kohlmeyer, Dawn DeDeaux, Dale Chihuly, Gene Koss, and the stunning, brazen figurative photographs of recently departed local George Dureau.
