America's Got Talent determined its five remaining sixth-season Top 10 finals acts during Wednesday night's live broadcast of the NBC reality competition series.

Silhouettes, an interpretive dance act from Arvada, CO; Anna Graceman, a singer and pianist from Juneau, AK; Landon Swank, a magician from Wasilla, AK; and Landau Eugene Murphy Jr., a singer from Logan, WV, were revealed to have finished as the Top 4 vote-getters after Tuesday night's performance show which featured 12 of the season's 24 semifinalist acts performing for home viewer votes, automatically earning them a spot in the finals.

America's Got Talent host Nick Cannon also revealed that gymnast group Gymkana, variety act The Kinetic King, hip-hop dance team Fatally Unique, jump rope team Summerwind Skippers, pole dancer and aerialist Steven Retchless, and shallow water diver Professor Splash had received the six lowest home viewer vote totals and been eliminated from the competition.

The announcements then left America's Got Talent judges Piers Morgan, Sharon Osbourne and Howie Mandel with the task of deciding which of the two acts that had received the fifth and sixth highest vote totals -- Smage Bros. Riding Shows, a motorcycle stunt show act from Elkhorn, WI, or Snap Boogie, a dancer from Boston, MA -- should become the fifth act to advance to the finals.

"I'd like to put them both through but I can't. I want to say that the Smage Bros., this is your life -- what you do. It's your family. It's a family affair. It's obviously your family's passion and you can see that passion. It's extremely dangerous. You put everything into it," Sharon said.

"[Smage Bros.], you've shown to me so many times in this show that what you do is incredible, and I love the fact it's a family affair. And Snap, what can I say about Snap? You've put out there week after week all on your own. You've not had a family affair. You've been doing all of this on your own. I know that you want to make a better life for yourself through your talent and you are blessed with an incredible talent. I love seeing you perform. It makes me feel good... That's why I am going to vote for Snap."

Piers then cast his vote for Smage Bros. Riding Shows.

"I'll make it quick. Before last night, I would have definitely voted for Snap Boogie over you guys. I thought he had more natural talent. He's more exciting. Last night, my thought process changed because of what you guys did. [Smage Bros.], you were sensational last night and I didn't really like Snap Boogie's routine. So the question for me is, 'Do I base my decision on everything before or just on last night?' And what I believe is really important now. I'm going to go with the Smage Bros.," Piers explained.

With the judges' voting tied, it was then up to Howie to cast the deciding vote.

"Snap Boogie, you are amazing. You've brought the street to the theater. Smage Bros., you brought the real street to the theater and risked your lives. How do you even compare these two? You're amazing, but what would I go and pay to see? What do I want to go and see? I want to see the Smage Bros.," Howie added.
