That is an instrument I have only recently become aware of---and it seems to me to be just a bit unwieldy---but of beautiful tone!
Here is a singer that I just became aware of as well. I first heard Helen Traubel sing (at least as I can recall) in a broadcast recently on PBS about JFK. There was a inauguration gala that was never broadcast because of a significant snow storm. PBS recently aired the recordings of that event and Ms. Traubel sang the Battle Hymn of the Republic marvelously. Unfortunately, this is only a short recording of her voice and I could not find the recording I heard on PBS.
