Sure, Brooklyn’s profile has been on the rise for years, but the borough still doesn’t have a worthy hometown orchestra. The Brooklyn Philharmonic has been moribund for its last few seasons, keeping off the cultural radar while focusing on educational outreach and small ensemble concerts. That’s all about to change. Alan Pierson, a noted figure in the new music scene, has been tapped to come in and turn things around. “I want the Brooklyn Phil to become an essential, dynamic force for music in the borough,” he told us. Hopes are high: like Maestro Alan Gilbert infused new vigor into the New York Philharmonic, so too, we hope, can our Alan do for us.
