A unique musical performance is underway in eastern Germany, where a small organ has been playing a single composition at a very slow pace. The piece, by composer John Cage, has been playing for nearly 25 years and is expected to continue until 2640. The performance is part of the John Cage Organ Project Halberstadt, which began in 2001.

The composition is scheduled to finish on September 4, 2640. Further details about this unusual concert are available from KSAT 12's source.
