Countertenor!

I just came back from a concert at the Herbst Theater, where I heard a countertenor -- David Daniels -- sing with the English Concert group.  The Concert was very, very good, and so was the singer.  Countertenors have an eerie quality about them, and it's sometimes hard to reconcile that the voice you are hearing is coming from the person in front of you.  Countertenors are basically male soprano's, but they aren't singing in a falsetto voice.  (At least, I don't think they are.)  I don't know how the voice is produced, but it can be astonishing, and very powerful.  Bravo!
