Eavesdrop> A Very Gehry Opera.  Walt Disney Concert Hall by Frank Gehry. Frank Gehry will return to Walt Disney Concert Hall this spring—as a set designer. He’s at work on a “moving still-life on the stage” for the Los Angeles Philharmonic’s May production of Don Giovanni. The plans call for moving the orchestra upstage on raised lifts, about four feet above the action taking place downstage. Meanwhile, in a recent Q&A with Wallpaper* magazine, Gehry revealed that things are “getting slow” for his firm, to the point that he is considering—gasp!—proactive PR efforts. “We’ve got enough things for the next year, but it’s not the same as it was a few years ago,” he said. “I’m old enough to quit, though, you know what I mean? I’m 82.”
