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

Some art-haters in the comments, so to defend this piece of contemporary art for a moment: one thing I love about it is a commitment to the long future of art, creativity, and civilization. What does it take to keep an instrument playing for six hundred years? To commit to that idea -- like the century-long projects of cathedral building in the middle ages, or the idea of planting trees you won't live to see mature -- is (to me) the awesome thing about the Halberstadt performance. All rendered in a medium (church organ) that has existed for an even longer time.

It's a pretty hopeful, optimistic view of the future in a time of high uncertainty, but also represents a positive argument: it's worth doing these things because they are interesting, weird, and fun, and because they represent a continuity with past and future people we will never meet.

Plus, you can already buy a ticket to the finale, so your distant descendants can go see it :)

It's a neat goal to keep an organ playing for hundreds of years. I just don't think that's related to the musical composition itself, which is not impressive to me. The fact that Cage added the phrase "as slow as possible" is not, in my opinion, musically interesting.

It would be analogous to writing a screenplay, adding the note "produce the film using as much money as possible," and then having someone attempt to do that. It's technically impressive to spend $500 million on a film production, sure, but that small note at the end of the screenplay is not cinematically interesting.

Cage created art that transcends music and you are rightfully noting that it is not that impressive when judged solely on musical merit.

It’s like saying a dodecahedron isn’t that impressive when viewed sitting on a 2D plane because it’s just a triangke and there are more interesting 2D shapes. True, but so reductive it’s tautological.
