Here is my daughter singing Tantum Ergo at voice camp. Unfortunately she has had a cold and couldn't practice at all, which kind of defeats the purpose of a voice camp, but at least we got to hear her sing at the recital:
I still have to upload the terrible quality vid I have of her singing O Mio Carro Babino, will add that in a bit.
Here is a vid of her doing O Mio Babbino Caro a few months ago at the school talent show. The quality sucks because my wife shot it on her phone and it was too dark for the autofocus to work. But the sound quality is ok.
