Who will win 'AGT'? Watch Drake Milligan's country smash, Sara James' haunting Kate Bush cover

On "America's Got Talent," it's all come down to these performances.

The penultimate episode of the season aired live Tuesday, with stunning performances from the eleven frontrunners duking it out for the win.

Drake Milligan crooned his heart out on an original country song, while Golden Buzzer winner the Mayyas raised the bar on their synchronous choreography. Sara James, another Golden Buzzer winner, performed a chill-inducing Kate Bush cover and Chapel Hart, also a Golden Buzzer winner, delivered a performance that inspired American patriotism, even in British judge Simon Cowell.

Here's what went down, including the feedback from judges Cowell, Heidi Klum, Sofía Vergara and Howie Mandel.

Kristy Sellars

First up, Kristy Sellars, who combines digital media with pole dancing, gave a magical performance that put her previous routines, which were already stellar, to shame.

By the time the Australian finished, Mandel's feedback couldn't be heard over the uproarious applause.

"You let us be part of your dreams, because it feels like we’re diving into your dream," Klum said afterward. "It’s stunning."

Vergara said the dancer keeps getting "better and better."

"You showed us something even more amazing than the last time," she aded.

Cowell said Sellars sure gave a tough act to follow.

"I’ve never seen anything like this before, ever," he said. "You were great when we first saw you, then you went to incredible, and now you’ve gone to amazing. This is what this final is all about. I really believe we have the best of the best."

Nicolas Ribs

French magician Nicolas Ribs delivered another performance in which he appeared to make several objects appear out of thin air.

Klum said ribs "invented a different kind of magic."

Cowell disagreed.

"Tonight, everybody has to be better than the performance we saw before. I don’t think that was," he said, to raging boos from the audience. "The music really bothered me. It reminded of an aunt playing the piano after lunch."

Mandel countered that Ribs "made the impossible possible."

"That was amazing," he added.

Chapel Hart

Country trio Chapel Hart were left in tears after performing their patriotic song "American Pride," which earned a standing ovation from Cowell.

"The chorus, the lyric was beautiful," he said. "After 9/11, what a beautiful message to send out on the most important night of your life."

Mandel wasn't as enthusiastic.

"America is gonna like that song, but the last two songs you did were 10 times stronger," he said.

Vergara said "there’s something about you girls performing as a group that makes everyone excited."

Mike E. Winfield

After Mike E. Winfield's stand-up set about parenting, Cowell called the comedian "magic."

"I love your voice," Mandel added, noting he wants to work with Winfield one day. "You come out here like a superstar."

Klum said Winfield has "an amazing look," and Vergara called him "a star."

Metaphysic

Metaphysic floored the judges once again with their deep fake technology, which they employed to show Elvis Presley singing alongside "AGT" judges Klum, Vergara and Cowell.

"Can we talk about how good I was?" Klum joked. "I don’t think i ever sounded this good in my life."

Cowell made a mighty prediction.

"You’re so creative," he said. "You’re gonna have your own show on Vegas. There’s no question."

The Mayyas

The Mayyas, a women's dance group from Lebanon who earned the Golden Buzzer from Vergara after their inspiring audition, raised the bar with a performance that saw them dancing with feathers in perfect synchronicity.

"There is nothing that I can say, because you guys are the best," Vergara said, before the rest of her feedback was drowned out by cheers.

"This is what a million dollar act looks like," Klum exclaimed. Tonight it was A+."

Cowell predicts the Mayyas are in for an impressive career beyond the show.

"This was astonishing," he said. "Something has happened with you, where I'm beginning to feel a buzz beyond the show. This has landed."

"Winner winner chicken dinner," Mandel exclaimed, as the crowd started chanting "Mayyas." "This is my favorite act ever on 'AGT.' "

Avery Dixon

Avery Dixon, who clinched host Terry Crews' Golden Buzzer, sought once again to prove his bullies wrong by shining on the "AGT" stage.

"I saw you last week, and I saw how excited you were to be ready for the final, and I saw this look in your eye," Cowell told the young saxophonist. "You’ve really, really nailed it."

Klum said Dixon "took all the roadblocks" in his way and made them work for him.

"I'm so happy for you," she added.

Celia Muñoz

For her ventriloquist act, Celia Muñoz played the part of a medium communing with the soul of the world's greatest opera singer. She provided all the voices of course, including a phone call that interrupted the seance.

Cowell called the act "clever, frightening, funny, creative."

Vergara said the act was "so fun," and Klum called Muñoz, who was voted into the finale as a wildcard after getting eliminated, a "rare talent."

"You’re like a classic vaudeville performer that we haven’t seen for years," Mandel marveled.

Sara James

Sara James, a teenage singer from Poland and Cowell's Golden Buzzer, delivered a haunting rendition of Kate Bush's "Running Up That Hill" that brought all four judges to their feet.

Cowell said James "nailed one of the most iconic songs in the world."

"You’ve just given yourself a shot after that," he added.

Mandel countered: "The thing is, a lot of people tonight have given themselves a shot."

Klum called James "one of our greatest discoveries this season."

"You have this freshness, this newness about you" she said. "You already look like a superstar."

Yu Hojin

Magician Yu Hojin seemed to do "30 tricks in three minutes," according to Vergara, who watched in awe as he seemed to make objects disappear and transform before the judges' eyes.

"You’re not a magician," she added. "To me, it feels like you’re magical."

Cowell, the only judge to give Hojin a no after his first audition, turned the magician's success into a compliment for himself.

"I sort of said no on purpose because in my mind I envisioned you in the final, and you’re here," Cowell said. "You are a brilliant showman. You’re very classy. You’re such a gentleman, and, more importantly, you’re a fighter."

Mandel called Hojin his "favorite magician this season."

Drake Milligan

Closing out the show was country crooner Drake Milligan. Milligan's had quite the success outside of "AGT." After each of his performances, the original songs he sang charted.

On Tuesday, Milligan sang his song "Sounds Like Something I'd Do," which he also sang for his audition. Afterward, he teased he'll be dropping more music later this week.

And he already has fans in the judges.

"I really think this is gonna be the start of your career," Cowell said.

"I already want to buy a ticket to your concert," Vergara exclaimed.

Klum called Milligan "the one to beat," and Mandel said it's between him and the Mayyas for the win.

"You just brought it home, and i think you’re a star," Mandel added. "That song is gonna be number one tomorrow."
