Paul Lehrman writes about the extended performance of George Antheil's
Ballet mécanique at the National Gallery of Art in Washington, D.C.:

  I haven't visited your site in a while, but saw this posting recently:

  A description of the installation, as well as a video of the complete
  performance (the piece was edited down to 10 minutes) is at
  http://antheil.org/ .  It was originally supposed to be on display for
  17 days, but it proved so successful that the Gallery kept it going
  for nine weeks.  QRS Music, Inc., supplied 16 Gulbransen player grand
  pianos, and the sound was incredible.
