Tobi Tobias comes back from Copenhagen’s Bournonville Festival with vivid impressions of the city’s new Opera House. “The Opera is masterly in its command of space and light and typically Danish in its harmonious juxtaposition of materials: glass (miles of it, it would seem), stone (in subdued shades of grey and sand that give it an eerie lightness), steely metal, and lovingly treated wood. The interior of the building continually echoes the curved shape of the façade. At the hub of the public space is a gigantic bowed form clad in glowing maple veneer. Fantasy suggests it’s the work of a violin maker operating on a Brobdingnagian scale.”
