Play it slow, let it blow.

In my village, the local musician, Kikobina!ot, creates beautiful music on his many instruments. His ballads keep me entranced for hours on end, and I feel like I never want to stop listening. However, even I would get tired of a song that lasts for over 600 years. Yet, the good people in Halberstadt, Germany, aim to make this song a reality. The piece, titled Organ/ASLSP, and composed by John Cage, is scheduled to be played for 639 years. This is real. I'm not making this up. The piece first began on September 5th, 2001, with a two year "rest", lasting until February 5th, 2003. It was then that the first chord was played, lasting for another two years.
The piece will be finished in the year 2640.
Perhaps my great-great-great-great-great-great-great grandson will experience the ending of this song, which gives a new meaning to the phrase "slow and steady."
