Ever so often, someone tells me that music is just the handmaiden of the liturgy - a phraseology with which I take great exception.
But there is one church where music is thought of as the hand of God. I remember when this organ was installed - it made the cover of the American Organist magazine (I don't recall the magazine's title - it's gone through several incarnations over the years).
This is not for the faint of heart, mind you. So take a puff on your inhalor, make sure you've got nothing in your mouth which can be spewed onto your monitor, and click this link. There is a translator somewhere on the web site, in case the link I've given doesn't do the automatic translation (which is not so hot, but better than trying to decipher it from the French - unless you're good at reading French, which after many years from high school, I'm not).
