We have become used to concert halls that make big bold statements: the looming sculptural forms of the Philharmonie in Paris, the metallic sails of Disney Hall in Los Angeles, the giant glass barrel vault of the Kimmel Center for Performing Arts in Philadelphia. The Kleinhans is curiously elusive. Approaching from the circle, one catches glimpses between the trees of a small drum embraced by a curved walkway and a reflecting pool. No windows and no entrances—there are two in this axially symmetrical building—are visible, just the drum and the pool. The main entrance is on the side, and it is a bit of a surprise since it is dominated by a long concrete canopy that, while structurally elegant, resembles a bus shelter. Mundane but useful; it was raining hard the day I visited, and I thankfully ducked under its protective cover.
