Somebody asked Renzo Piano what is was like to design an addition–the Broad Contemporary Art Museum–to the Los Angeles County Museum of Art. “As I already told you, it’s very frustrating to play a good piece by a string quartet in the middle of three badly played rock concerts,” he responded. As I wrote in Slate: “Piano was referring to the existing museum buildings, whose architecture is pretty bad, as if a shopping mall had been converted into a cultural facility. But after sitting in the outdoor cafe, watching groups of excited children running across the roofed plaza and teenagers wandering in off the street, it struck me that this vulgar (in the literal sense of the word) Southern Californian solution to an art museum succeeded in one important way. In part because of its lack of pretension, this is an art museum in which people appear decidedly at home.” I wasn’t much impressed by Piano’s string quartet, but the rock concert struck me as a pretty  interesting place. Now LACMA has announced a $650 million plan to demolish the three old buildings (a pavilion by Bruce Goff will be preserved) and replace them with a brand new museum designed by Peter Zumthor. Most critics admire Zumthor’s work, and the project has generally been greeted with accolades. I’ve never warmed to his pious brand of minimalism, but this project strikes me as misconceived not because of what will be built, but because of what will be lost. The old LACMA is a refreshingly quirky setting for art; neither palatial, like the nineteenth-century museums, nor primly aesthetic, like most new museums. It would be nice if LA stopped continuously trying to re-invent itself.
