America’s Got Talent top six acts performed one new act and one repeat performance in Tuesday night’s live episode, and the winner will be announced on the live finale, Wednesday, Sept. 17.

Quintavious Johnson

Quintavious Johnson, the 12-year-old with the big voice, kicked off the night with his repeat performance of Etta James’ “I’d Rather Go Blind.” Judge Howard Stern loved it, calling him “a real pro at 12-years-old.” Heidi Klum agreed, saying, “You really are a true entertainer. I love that.”

Johnson later performed “Let It Be” for his final performance, and the judges, again, went wild for the young singer. “You are a star. Another star performance, another winning performance…America cannot let it be, they need to vote,” said Howie Mendel.

Mat Franco

For his repeat performance, Mat Franco, the last magician left in the competition, did a new rendition of his audition hidden ball trick, complete with a story about all the judges getting drunk in a bar.

Franco later performed an impressive, new card trick requiring the assistance of judges Mel B and Howard Stern. The magic man used Stern and Mel B to order cards into red and black piles based on intuition. When the two sets of cards ended up being identical, Stern was certainly impressed, asking, “How did I do that?!”

The judges agreed that Franco never failed to impress them with his magic, and complimented his charming talent as a storyteller. “I have to say, every time you shock me! You make magic become magic. You are great,” Mel B told him.

Emily West

Emily West, one of Stern’s early favorites, performed Sia’s “Chandelier” for her repeat, taking the stage in a glamorous red dress. West’s performance was a winner for most of the judges, but Mel B wasn’t completely sold, telling her, “I have to be really honest, I much preferred it the first time around.”

West changed it up a little bit for her final performance, singing Robert Flack’s “First Time Ever I Saw Your Face.” West abandoned the theatrics for the performance, appearing alone on stage, and Mel B was quick to change her tune on West, saying, “That was off the chain! If that can’t win you a million bucks, I don’t know what can!”

Miguel Dakota

For his repeat performance, Miguel Dakota performed his cover of “Seven Nation Army.” The performance offered a nice contrast to his “Billie Jean” cover, as he decided to leave the guitar playing to the band, and instead chose to rock out on stage, accompanied only by a crazy light show.

Mel B told Dakota she felt his nerves him his performance, but she also said she sees the star quality in him. “You’ve got that extra something. I do hope America votes for you, but it’s going to be tough not going to lie.

Dakota, an early favorite, chose to perform a stripped down cover of Michael Jackson’s “Billie Jean” for his last turn on the America’s Got Talent stage.

The judges applauded Dakota’s risky move, and Stern said that it was a perfect way to end Dakota’s time in the competition, as it showcased what he does best: “I think this was your best performance, and I always think you are strongest with just your guitar and singing on stage.”

Sons of Serendip

Sons of Serendip performed their cover of Keane’s “Somewhere Only We Know” for their repaeat, and had the judges showering the group with love, but Stern pointed out that they might not be what America is looking for. “If you don’t win, I think it is an image problem. You have pure, raw talent. Image wise, you are not the ‘it thing,’ you are sort of retro,” Stern told the group.

For their final performance, the quartet interpreted Evanescence’s “Bring Me To Life.” While the judges were impressed, none of them appeared confident that Sons of Serendip would win the competition, though Mel B did tell the group she would buy their album “right now, right now!”

AcroArmy

AcroArmy, the final act to take the stage for the repeats, re-staged their semi-finals performance, “The Immortals.” The acrobatic dance group wowed the judges, yet again, and Klum even said she wanted them to win the whole competition, saying, “You deserve a show in Vegas and I can’t wait to see it!”

In their final performance, AcroArmy created a new crazy routine to Fall Out Boy’s “My Songs Know What You Did In The Dark.” The judges gave the performance a standing ovation, and Mendel told the acrobats, “That performance alone was a winning performance.”

The winner of America's Got Talent will be announced on the finale, Wednesday, Sept. 17 at 8 p.m. on NBC.
