Grace and Josh visit 'After Impressionism', an exhibition at London's National Gallery to learn and see how modern painting developed in European cities other than Paris, principally Berlin, Vienna, Barcelona and Brussels. Acknowledging the achievements of Cezanne, Van Gogh and Gauguin in taking modernism beyond the Impressionists, the show demonstrates the contributions of many significant modernist painters some of whom have been neglected or infrequently exhibited.
