I know they've come under a lot of criticism lately, but I have to admit I'm hooked on these TV talent shows. American Idol, The Voice, America's Got Talent -- I watch 'em all, and I never cease to be amazed at the incredible talent.

Would Carrie Underwood have been discovered were it not for American Idol?  Kelly Clarkson was the first American Idol. How about Miranda Lambert? We first saw her on Nashville Star.

I always wonder if any of them would have become the mega stars they are today without the exposure on national TV. So that's why I sit through the ridiculous wanna-bes for a look at some really talented people.

This past week on America's Got Talent, three guys walked out and sang together publicly for the first time. By looking at them you just wouldn't expect it, but they blew me away. They surprised the audience and the judges. They're definitely not country, but really worth listening to. Check 'em out.
