"639-Year-Long John Cage Organ Performance Changes Chord for the First Time in Two Years"
In Halberstadt, Germany, a 639-year-long performance of John Cage's piece Organ2/ASLSP (As Slow as Possible) is underway, with the sound changing for the 16th time after two years. The wooden-framed organ, played since 2001, is a work in progress, with metal pipes added or taken away with each chord change. Despite numerous mistakes and challenges, the John Cage Organ Foundation remains committed to the performance, which is scheduled to continue until 2640.
