Absolutely amazing... you'll never see anything like that on an American talent show, most Americans (myself included) are way too lowbrow for opera. That man can REALLY sing, voices like that are probably literally one in a million.
My dad had two singers he listened to. Mario Lanza and Johnny Cash. Two great performers in their own right but totally different styles and genres. Mario had a voice that was pure and pitch perfect. Johnny on the other hand doesn't have a great voice but I love the subtle nuances of his voice that are probably overlooked by most people.
My favorite singer/songwriter is Leonard Cohen, not widely played in the states, and a voice that also takes a little getting used to, but he's a songwriter extrordinaire. Simply touches my life and heart in so many ways.
