Query: Dark & Mysterious

This music by Tomas Victoria & sung by Westminster cathedral is beautifully sung & produced, but is not what you might call an upbeat, happy piece. It is quite dark & meditative, which such a mystery should at times invoke in addition to the outright joy one feels at the birth of our Savior. I will say that certain movements of the music are a little boy-soprano heavy, making it a bit squealy. By far, though, it's glorious & beautiful.
