The World’s Longest Running Performance Will End in the 27th Century. A 639-year performance based on eccentric composer John Cage’s “As Slow as Possible” (ASLSP) started in September 2001 and is still playing at St. Buchard Church in Germany. The performance by an automated organ plays so slowly that visitors have to wait months for a chord change, and is scheduled to end in 2640. The performance is so slow that the organ it’s played on was not even completed before the concert began. Additional pipes were added before the notes and chords changed. A generation of musicians will need to keep the organ going!
