At long last, the Kennedy Center Concert Hall is getting a new organ to replace the decrepit Filene Organ that has for some years been virtually unplayable. The announcement was made on Sunday night from the stage of the concert hall at the gala season opener of the National Symphony Orchestra. Too: Christoph Eschenbach is extending his contract as music director of the Kennedy Center and NSO by two years, to 2014-15. The full story is here: Kennedy Center extends Eschenbach’s contract; new organ in works, by Anne Midgette.
