Jacques Herzog and Pierre de Meuron, like many of their starchitect brethren, have not had an easy time of late in New York, from the stalling of 56 Leonard to the continuing reconfiguration of the Parrish Art Museum. (Yes, we know everybody’s having a hard time of late, but that’s a different story.) Well, the Basel-based architects just got their big break, as they say in the theater: a debut at the Met. No, they are not the latest hot shot firm to proffer an addition to the ever-transforming complex. Better yet, they’ve designed the set for a new production of Verdi’s Atilla, which premiers tonight. We’re not exactly sure what to make of the ghostly scenery that somehow floats above the chorus, from a forest picnic of sorts to post-apocalyptic-looking ruins (hopefully not the remnants of some failed project). Yet even in this unusual setting, the designer’s unusual forms shine. Fashion doing about as well as architecture these days, does it come as a surprise that Miuccia Prada has lent her talents to the costumes? With any luck, Herzog & de Meuron will take over the Oscars next year.
