The top six finalists on "America's Got Talent" performed Tuesday, their last time before the Season 9 winner will be crowned. Their final performances before the judges and voters included a past act and brand new performances.

Each performer was given two times to draw attention for their last chance on stage.

The first round of talent included 12-year-old singer Quintavious Johnson belting out a number that he performed earlier in the season, Etta James' "I'd Rather Go Blind."

"I'm feeling Quintavious all over the place," judge Howard Stern said. "This guy takes the place and he owns it, he is a real pro at 12-years-old, I think he really has a shot."

Mat Franco, a magician-comedian-of-sorts, returned to an act he did in auditions for "America's Got Talent," but provided a new take on the performance to update it. His story centered on an illusion that involved drink shakers and balls, and incorporated a comical story of three of the judges: Stern, model and host Heidi Klum and game show host and comedian Howie Mandel.

Mandel's feedback of the performance: "I think you have everything, you have the whole package, charisma, you can tell a story and the way you present your talent is amazing!"

Another singer in the group Emily West sang her own version of Sia's "Chandelier." Stern, 60, called it "a winning performance." The final judge on the panel, former-Spice Girl Mel B, didn't think it was as stirring of a rendition.

"I have to be really honest, I much preferred it the first time around," she said. "You are still a killer singer, and half way into it you nailed it."

Miguel Dakota, 19, sang The White Stripes' rocking "Seven Nation Army," but the judges felt the pressure of competition was felt in his performance. The group Sons of Serendip covered Keane's "Somewhere Only We Know," and Mel B and Howard both agreed they deserved to win it overall.

"If you don't win, I think it is an image problem," Stern commented. "You have pure raw talent, image wise you are not the 'it thing' you are sort of retro. If you don't win, that's too bad because you have such talent."

The last finalist was the ArcoArmy, who repeated their semi-finals performance of "The Immortals." This time, Klum, 41, was rooting for them undoubtedly.

"You really deserve to win this thing, it's unbelievable and if you don't win it's because television is limited...you deserve a show in Vegas and I can't wait to see it!"

The group then each gave another brand-new performance to showcase their talents one last time. The finale airs Wednesday, Sept. 17 on NBC.
