A new chord was scheduled to sound in the world's slowest and longest lasting concert that is taking a total 639 years to perform.Nifty additional details about the site:
The abandoned Buchardi church in Halberstadt, eastern Germany, is the venue for a mind-boggling 639-year-long performance of a piece of music by US experimental composer John Cage (1912-1992).
Entitled "organ2/ASLSP" (or "As SLow aS Possible"), the performance began on September 5, 2001 and is scheduled to last until 2639.
That original organ, built by Nikolaus Faber for Halberstadt's cathedral, was the first organ ever to be used for liturgical purposes, ringing in a new era in which the organ has played a central role in church music ever since.
As part of Halberstadt's John Cage Organ Project, a brand-new organ is being built specially, with new pipes added in time for when new notes are scheduled to sound.
I'm not sure that this *is* the longest John Cage concert, actually. The Trappist Order, whose members take a vow of silence, was founded in the 1600s, so they have, collectively, an almost four-hundred year head start on continuous performance of the (very!) extended dance remix edition of 4'33".
