Sometimes I check if the German site where John Cage’s Organ2 / ASLSP is being performed, expanded to an incredible 639 (six hundred and thirty-nine) years, still exists and the answer so far is yes.

To find out more about this epic execution that began in 2001 and destined to end in 2640, I refer

• to my 2006 post which was the first entry of this blog
• to this wikipedia page dedicated to composition
• to the German site where Organ2 / ASLSP is running

Finally, here you can hear the epic 2006 note change at 8:36 in this audio clip. The last was in 2013 and the next is expected on September 5, 2020.

This is the organ used for execution.
