The Cathedral of the Madeleine. The acoustics are ridiculous. A while ago I attended a men's choir performance. When I heard their voices and the organ.. I seriously felt like I was in heaven. (It was closed when I went to photograph, but the inside is magnificent.)
This works perfectly for the corner view, because this cathedral is within walking distance from our apartment. And it's cool because it's a Utah Historic site.
Experience music all around the world.. (see jane for the links)
