Musicians and supporters of the nearly-dead Florida Philharmonic have been scrambling to put together the funding necessary to save their orchestra or, at the very least, give it some financial breathing room until a more permanent fiscal plan can be realized. But after starting strong, the rescue mission has stalled badly, and its organizers admit that they’re running out of time. By the end of this week, the orchestra’s board, which many musicians have accused of running the organization into the ground, may decide to convert the company’s bankruptcy filing from Chapter 11 to Chapter 7, which would mean a final, permanent shutdown.
