  The Self-Contained Hootenanny

  This is the autonomous mechanical band that uses 17 instruments
  built into its cabinet to generate a verifiable shin-dig.  Housed
  within a handcrafted oak cabinet, the machines instruments are
  played by a system of precisely calibrated pneumatics that strum
  and pluck strings while thumping and tapping drums.
