Last night on America's Got Talent, light artist Alex Dowis, paid tribute to the first responders of New York City after the horrific terrorist attacks of September 11, 2001.
Alex is a street artist from the Czech Republic. What he does with light on a consistant basis is amazing, but last night he moved, the judges, the crowd and the country with his emotional tribute to first responders.
Julianne Hough fought to find the right words and she said to Alex: "...you represent that you can't have light without the dark."
It was a very moving, emotional performance and you can see it below.
