I guess we won't have a player piano version of the Cowell Piano
Concerto, which I saw last evening at the San Francisco Symphony:

  Henry Cowell's Piano Concerto, which Tilson Thomas enjoys calling
  a "swashbuckling" work in the Romantic tradition. The soloist's part,
  however, is worthy of the Ramones or jazz avant-gardist Cecil Taylor:
  a torrent of crashes and clusters, smears and "great splodges of
  notes," played with fist and forearm.
