NEW YORKThe New York Philharmonic Orchestra announced Monday that it will continue its popular open-mic nights throughout the 2005 fall season, encouraging everyone to 'bring nothing but your instrument, 10 bucks, and whatever talent God gave you.' According to director Lorin Maazel, 'There are a lot of people out there with a cello or an oboe but no one to play with. Come on stagewe know over 500 symphonies! But please, no stand-up.' Highlights of last year's open-mic nights included Mr. Maazel conducting data-entry technician Stacy Peterson and auxiliary-equipment operator Dan Fowles in a performance of Brahms' Double Concerto in A minor.
