The New York Philharmonic is the oldest active symphony orchestra in the United States, organized during 1842. Based in New York City, the Philharmonic performs most of its concerts at Avery Fisher Hall. The orchestra is older than any other American symphonic institution in existence by nearly four decades; its record-setting 14,000th concert was given in December 2004. Since 2002, the Philharmonic's music director has been Lorin Maazel, whose tenure is scheduled to conclude at the end of the 2008-2009 season. Starting with the 2009-2010 season, Alan Gilbert is scheduled to become the Philharmonic's next music director.
