Crystal Bridges Museum of American Art, Bentonville, Arkansas
The National Gallery has done it again: a small but perfectly formed exhibition in their little Room 1, now a by-word for intelligent show-making. Something new, something revelatory, something profoundly beautiful – what more can the gallery-goer ask? The Ashcan School is not widely known outside the USA, and I can think of no better introduction than this dozen-canvas-strong showing of some of the highlights (and, it must be admitted, a couple of low-lights as well).
