"Another note from a piece by a US composer has been played in what has been called the world's slowest and longest concert.
The church organ in the German town of Halberstadt played the next - seventh - chord of John Cage's As Slow As Possible work.
The performance began in 2001 and is scheduled to last a total of 639 years."
