“A new chord has sounded in the world’s slowest and longest concert, which will take 639 years to perform.
An abandoned church in eastern Germany is the venue for the 639-year-long performance of a piece of music by American experimental composer John Cage.
The performance of “organ2/ASLSP” (or “As SLow aS Possible”) began in the Buchardi church in Halberstadt on September 5, 2001, and is scheduled to last until 2639.
The first year-and-a-half of the performance was total silence, with the first chord, G-sharp, B and G-sharp, not sounding until February 2, 2003.” (ABC.net.au)
