John Cage

1953 - 1958
As Slow As Possible was composed by John Cage, arguably the most influential American composer of the 20th century. It was originally a 20-minute piece for piano, but later expanded by some crazy group of theologians, musicologists, philosophers, composers and organists to an unbelieveable 639 years. Yes, that means the song will take 639 years from start to finish. It was first played sometime in 2003, on a church organ in Halberstadt, Germany.
