@alice I LOVE this piece. I think it was on tour with a show called You Are Here: Light, Color, and Sound Experience some years ago. I saw it once at the NC Art Museum.

I remember the artist statement too-- IIRC it was something to the effect of the artist was trying to find a way to capture the feeling of sacredness and immense beauty that they saw in their (masque?) growing up, and wanted to make any room feel just as sacred. I'd say this did it!
The exhibit this was on tour with also had a room with like 50 speakers, each one tied to a single singer as everyone was singing in chorus. You could kind of walk around the room and experience each unique voice during the song.
I hope that exhibit heads your way soon too! It's worth a listen.
EDIT: Upon further inspection, I can see that this is a slightlg different piece, though it may be the same artist? Not sure, but still cool.
