A short, interesting article appeared today in National Review about
pianist Maurizio Pollini's recent performance in Carnegie Hall and the
juxtaposition to the performance of a player piano.  It even mentions
the "famous Ampico B".

  Pollini and the Player Piano
  By Daniel Gelernter
  Musical brilliance is not the same as mathematical perfection.

Ann Donoghue

 [ The articles opening includes this statement about piano rolls:
 [
 [ "[Aeolian] began to apply what was later called 'quantization' as
 [ a standard part of the editing process for new piano rolls.  The
 [ results were as neat as a pressed shirt, but they sounded odd:
 [ the notes were all there, but somehow the music had gone missing."
 [
 [ Like critics who complain that the Duo-Art 16 levels of expression
 [ aren't adequate, the writer should ignore the technical trivia
 [ and instead listen to piano roll performances with open ears and
 [ closed eyes!
