A minor chord change in one of the world's longest concerts

This week marked a chord change in one of the world's longest concerts. The 639-year performance of John Cage's Organ2/ASLSP (As SLow aS Possible) in a disused church in Halberstadt, Germany, has been going for 25 years. This is the first change since 2024, and the first under new leadership as the project's stewards plan for the next six centuries. Reporter Gabe Bullard has the story, from Halberstadt.

A piece about this and other long-term art projects will appear in an upcoming issue of the The European Review of Books.
