John Cage recital set to last 639 years recently witnessed a chord change

This is the same guy who wrote 4'33", the silent piece.

I kinda get that -- the 40000 Hz podcast gave it some good context:

Maybe they'll also explain the point of this. The piece is called "As Slow As Possible", but it's not as slow as possible. The slowest possible piece would have a fermata with an infinity sign over the first note, and that's it. Maybe the rest of it would be a jaunty little tune that would never be played in context. ("Shave and a haircut", perhaps?)

As a stunt, it's moderately interesting. How do you set up a contraption to play for hundreds of years? How do you maintain it without interrupting the performance? But it's less interesting than the 10,000 year clock.

Adam Neely and his band Sungazer did an interesting live experiment with his audiences, to figure out the slowest beat or pulse that people would be able to "feel" and dance to. Slowest possible isn't really as interesting in my opinion as slowest practical, which I think Neely and co's experiment explored. The track was Threshold on the album Perihelion.

The whole album explored beat, pulse and timings as it relates to how people can actually feel and interact with music. Really interesting!
