Since the demise of the Florida Philharmonic two years ago, observers have been wondering just exactly who the under-construction Greater Miami Performing Arts Center is being built for. Now, an answer has emerged, courtesy of the chairman who presided over the Phil’s disbanding: the center will open in 2007 with a 3-week residency by the Cleveland Orchestra. It’s good news for South Florida music lovers, of course, but some former Philharmonic musicians are furious, suggesting that chairman Daniel Lewis, who has given $12 million to the Clevelanders over the years, allowed the Phil to die knowing that he could bring in a visiting orchestra more cheaply.
