Every year I wait for Holy Thursday so I can hear this piece. I die every time I hear it. Tonight I heard it sung by the Dominicans at the Dominican House of Studies in Washington, D.C., and I think it was one of the best performances I have ever heard (if you can call it a performance, they were praying it, not singing it, that makes a huge difference). Sadly I wasn’t able to capture it, and it doesn’t really matter anyway, so much of a piece of music is lost when it is recorded.
