He is perceived as real, down to earth, appreciative, and humble. He sells out about everywhere, and gets rave reviews wherever he tours. He has a simply gorgeous and powerful voice, and can turn on a dime to break your heart and wring tears from his audience. Everyone that I have personally talked to that has hear him live says that he is even better live than on CD. I refer you to his Awake Live concert in SLC on Youtube.
I know of very few that can sing in such a variety genres, (believe me, he can sing country with the best, and swing and jazz like Buble if he wants to), and in so many languages (French, Italian, Spanish, Portuguese, and can speak some Japanese), and do all so well. In any calendar year, he could be composing, singing with friends in a night club, touring to sell out crowds in the biggest venues, working on a TV series, hosting a TV show, or singing with the Boston Pops or New York Philharmonic. He can go from singing “You Raise Me Up” to singing with Opera star Rene Flemming with the New York Phil at the drop of a hat if he had to (See his Youtube appearances singing Italian cinema with the NYP).
