For his recently released album Bromst, Dan Deacon and his crew programmed a player piano to play musical lines much faster than humanly possible, although still within certain mechanical limits. Pitchfork TV made a neat behind-the-scenes documentary about the making of the album – here is the section going into detail about the MIDI-controlled player piano. (I was a big fan of his last album Spiderman of the Rings – Bromst is a denser listen, but it’s growing on me.)
