Written by the late American composer John Cage, As Slow as Possible has been playing at the St. Burchardi church in Halberstadt, Germany since September 5, 2001. ‘Played’ is perhaps to strong a word to describe the sound coming out of the organ built specifically for this musical piece, as the performance began with a pause that lasted until February 2003, and has since continued with single notes played continuously for several months, sometimes years.
