A 639-Year-Long John Cage Performance Had Its First Chord Change In Two Years

One of the longest-running musical performances in history witnessed its first chord change in over two years on August 5. This most recent chord change, the seventeenth in the piece, saw the preceding C, D-flat, D-sharp, E, A-sharp and E chord turn into a C, D-flat, D, D-sharp, E, A-sharp and E, with an additional D note. The sixteenth chord change was observed in February 2024, over 900 days ago. Over 150 people crowded into the church before the chord change. The next chord change is expected on October 5, 2027.
