This is 99% invisible. I'm Roman Mars.

When you go to a concert, you might try to get there right when the door is open.

Or maybe you take your time and skip the opening act.

But generally, you want to be there when the show starts.

In February everyone who went to a concert in Harberstot Germany showed up 23 years late. All right.

Getting ready to head to the train station.

One of those late comers was Gabe Bullard,

Gave's reporter living in Basel, Switzerland.

So he took the train a few hours into Germany to a pretty rural part of the country.

Alberstadt is an old medieval town like what you'd expect from a storybook.

There are timber frame houses packed close together, curving cobblestone streets, but there wasn't time for sightseeing.

The concert was well underway.

And Gabe was planning to leave early because from this concert,

everyone walks out early. It's a performance of a piece called

Oregon 2 ASLSP. ASLSP stands for as slow as possible which is how the composer meant for it to be played.

And that's how it is being played, very slowly.

And the reason I came all the way to Halberstadt now is because this was no ordinary day of the

performance. I came to see a chord change. The last time organ 2 ASLSP had a

chord change was 2022 and this new chord will play until the next change in August of

2026 there's a change the year after that and the year after that and so on until the

year 2640 the full performance is meant to last

639 years. Walking up to the concert looks like this is it. Gonna walk in. The performance is in the Church of a Nuns Cloister, founded in the 13th century.
