John Cage's composition, 'ASLSP,' 'As Slow As Possible,' Lives Up to its Name

John Cage, late composer of experimental music, created a composition that is planned to take over 600 years to perform. A specially rigged organ in Germany has been playing the piece since 2001, and recently struck a new chord after two years. The challenges of performing this composition over centuries, including mishaps and mistakes, are explored by the John Cage Organ Foundation.
