The judges perform.
The three acts still standing on NBC's The Voice sang for the championship on Monday night, and whoever wins will be making show history in some way: The Swon Brothers would be the first winning duo, Danielle Bradbery would be the youngest champion crowned to date, and Michelle Chamuel would be an introductory win for first-time coach, Usher.

The finals kicked off with the four coaches teaming up for The Beatles' "With a Little Help From My Friends," with Usher and Shakira meshing incredibly well with Adam Levine and Blake Shelton. Hopefully these two newbie coaches rotate back into the red chairs on a future season. The top three also took the stage together for "Home" by Edward Sharpe & the Magnetic Zeros, alongside their fellow season four contestants.
Shelton had two acts in the the season finale -- putting him exactly where he was at this point last season, which he eventually won with country crossover Cassadee Pope -- while Usher stayed strong with one singer. Here's how they vied for votes, one last time:
Team Blake
The Swon Brothers -- the first duo to ever make it to the finals on The Voice -- put their harmonies at the forefront with The Eagles' "I Can't Tell You Why," with Zach Swon on the baby grand and Colton Swon on guitar. "I was pretty critical of the last Eagles tune you did, but I gotta say ... you guys did an amazing job," said Levine.
The singing siblings, who have stayed true to themselves, each other and the classics of their genre all season long, were asked to bring back Anne Murray's version of "Danny's Song." They happily collected the exact same praise as when they performed it last week. "You guys did it such justice, it's almost like I disappeared for a moment and we weren't here," commended Usher. The boys then picked up their guitars for Brad Paisley's "Celebrity" with their coach Shelton and a ton of tongue-and-cheek humor.

Bradbery -- the 16-year-old who has been successfully reviving country classics and, Shelton says, has earned the respect of Nashville -- gave an encore performance of Pam Tillis' "Maybe It Was Memphis," while rocking another fabulous pair of sparkly cowboy boots. "You have just gone straight to the vein of America -- 'atta girl!" cheered Shakira, while Levine expressed for the millionth time that her voice is perfect and he's insanely jealous of Shelton for nabbing her at the blind auditions.
She took a final shot at an up-tempo track, "Born to Fly" by Sara Evans. Though she may not be kneeling onstage like Chamuel does, the purity of her voice -- and character -- has repeatedly translated country's appeal to the Voice's audience. "You, my friend, are definitely a special thing," said Usher, while Levine joked yet again, "Your perfection is beginning to bore me at this point!" She also blended well with Shelton onstage for "Timber, I'm Falling in Love" by Patty Loveless.
Team Usher
Chamuel first reprised her theatrical rendition of Taylor Swift's "I Knew You Were Trouble," which was just as fresh as the first time she debuted her rendition, yet traveling across the stage with much more confidence. Her growth as an artist is self-evident -- for someone who couldn't even sing in front of her family, it looks like all the times Usher put her through out-of-the-box exercises have paid off.
Then, the "anything is possible if you just believe" archetype of the season returned to her vulnerabilities and emotions (and her mirror motif, with a twist) for "Why" by Annie Lennox. Though more physically subdued this time, she again proved that performing a song requires singing, acting and body language for a multidimensional show. "People should know that you're such a humble and sweet person," praised Shakira, "and when you have humility on one side and talent on the other hand, that makes the perfect recipe for long-term success." Chamuel then harmonized with her coach onstage during "One Love, One Life" by Beres Hammond.

Shakira, who declared herself a cheerleader for the evening, switched between Chamuel-style glasses, an Okies flag for the "Swon-cert" and a cowgirl hat for Bradbery. However, Levine didn't bother hiding his alliance -- the Maroon 5 frontman openly expressed that Bradbery is going to be called the season four champion.
But that's for America to decide -- the winner will be crowned Tuesday night at 9 p.m. on NBC. The special two-hour finale will feature OneRepublic, Bob Seger, Bruno Mars, Pitbull, Christina Aguilera, Florida Georgia Line, Nelly and Hunter Hayes, as well as a highly anticipated guest performance by Cher, who will perform her single "Woman's World" off her upcoming album of the same name and mark her first live performance in more than a decade.
