Waterloo native Emily West gave her most powerful performance yet this week on the NBC TV show 'America's Got Talent'. The show is currently down to its 12 finalist. Emily's performance of “Chandelier” by Sia had the judges on their feet.

Mel B was impressed with how Emily “made the song her own,” looked “stunning” and “sounded incredible.” Howie called West “the best act of the night.” Howard thought she did justice to the song and had the look to go with it. Heidi thought Emily was “a star” and “the total package.” Check out Emily's performance here.
