Decide who from YouTube will perform on America's Got Talent

The submission phase of our America's Got Talent contest has closed, and now comes the important part: Vote for your favorite YouTube performer here and one grand prize winner will perform live on the August 10 episode of the NBC show.

From the looks of it, some of YouTube’s most talented and quirky entertainers -- from upside-down piano players to accordion-playing dogs -- have entered the fray. There are 40 acts in all to choose from, and voting ends on July 4, so you only have a few days to help decide the destiny of one of these aspiring stars. Good luck to all contestants!
