Not the same thing. I was actually in that church, and while I would hesitate to describe what I witnessed as music, the atmosphere was really special. It’s a great installation and performance art at the same time. Plus, entry is free, so nobody can feel cheated. I find the whole thing interesting on a philosophical level - if we as a society can agree to uphold this for 600 more years (and hope to not have the church destroyed by some war) we must not be having many problems. To me, that’s an uplifting thought.
