Turns out his name is Alessandro Safina. I rented the DVD of Sarah Brightman's 2008 concert titled "Live in Vienna" and had to scoop my jaw off the floor when he started singing. Normally opera singers voices are somewhat annoying because they sound so affected, but there is this incredible tone to his voice, it's so rich and full. Makes my heart all fluttery :) I've been looking up other vids of his performances and I have to say, he does seem a little bit in love with himself; but, if I sounded like this, I would be in love with myself a bit, too. :)
This is the first song they sing (of 2) together called "Canto Della Terra"
Okay, so this music video is super cheesy, but just don't watch. Just listen :) "Luna Tu" (Only You)
