@DialMforMara Whoever told you that was wrong. I was in Halberstadt a few months after the last chord change, and that one's still going--the next chord change is in 2020. The piece did start with something like an 18 month rest, though.
@DialMforMara You can hear the current chord on the official website, btw: http://www.aslsp.org/de
It's different in person, though. The sound fills you after a while. Not due to volume--it was surprisingly quiet--but simply because your whole body will start to vibrate to the sound.
@DialMforMara Aaand I've totally side-tracked from the point of your post. Apologies. It would totally be cool to see a story about that.
@auntiekiki
They got the 2020 date right
