"America's Got Talent" finishes its Season 9 run Wednesday with a new winner taking home the million dollar award and future Las Vegas gig. The winner will be unveiled at 8 p.m. ET/PT on NBC TV.

Six remaining acts vying for the prize will learn their fate by way of a viewer vote. Twelve-year-old singer Quintavious Johnson was considered the front-runner, according to critics. Other competing finalists include singers Emily West and Miguel Dakota, street magician Mat Franco, singing groups AcroArmy and Sons of Serendip.

The final six contenders took the stage Tuesday to great acclaim as they sought to firm up support with one more round of performances.

Johnson kicked off festivities with a big voice rendition of Etta James' classic song "I'd rather go Blind." Judge Howard Stern said Johnson "owned it" and really had a shot. Fellow judge Heidi Klum called Johnson a true entertainer.

Franco reprised a previous act, but with some twists. Judge Howie Mandel called it entertaining and engaging while Stern said he had the entire package including charisma and great talent.

West sang the popular Sia song "Chandelier" while wearing an old Hollywood-style dress. Stern liked the performance calling it a winner. Judge Mel B. said she wasn't impressed although West did a good job at the end.

Dakota reprised the White Stripes "Seven Nation Army." Mel B. said the singer was nervous and probably couldn't win. Stern agreed, saying the song was good, but probably not enough to carry the vote Wednesday.

Sons of Serendip did Keane's "Somewhere Only We Know," on a candlelit stage. Mel B loved it, saying America should vote for them. Stern said they had a lot of raw talent, but maybe were a bit to retro to win it all.

Final act up Tuesday was AcroArmy. They reprised their semi-final performance of "The Immortals." Klum said they really should win the competition and deserved a Las Vegas show.
