and Adam Levine
did something on Tuesday that no Voice
judges had ever done before – they stole back singers who they'd previously cut loose in the battle rounds.
Thanks to a new twist, the coaches were each given one steal during this week's knockout rounds – the final hurdle before the live shows kick off next week.
Levine grinned like a schoolboy as he pressed his button for Will Champlin, a young dad whose father is Chicago band member Bill Champlin.
Champlin delivered an emotional rendition of "When I Was Your Man" by Bruno Mars that earned high praise from the coaches but wasn't enough to defeat fellow Xtina teammate Matthew Schuler, a Pennsylvania college student/indie rocker who had the crowd – and the coaches – roaring with his high-energy version of "Cosmic Love" by Florence and the Machine.
Aguilera initially seemed skeptical of Schuler's song choice, but ultimately stood up and pumped her fist at the end of his performance. "There is just something so magical about him when he sings," she said of her decision to choose Schuler.
Champlin, who joined Team Adam
after his blind audition, only to be stolen by Aguilera
in the battle rounds, got another chance at stardom when Levine pushed his red button.
"To steal somebody back that you wanted to keep, it's very cool," the Maroon 5 singer said.
Aguilera plainly felt the same way as she gleefully slapped her button to save Stephanie Anne Johnson (again!
) after coach Cee Lo Green
chose opponent Tamara Chauniece.
Chauniece, a leasing agent with a gospel background, flew under the radar earlier in the competition but blew the judges away with her reggae spin on "No One" by Alicia Keys.
Yet Aguilera couldn't help but be drawn in by Johnson's funky version of Norah Jones's "Don't Know Why."
"I loved every second of it," she said. "I thought you owned it."
Another performer who owned it? New Jersey high school student Caroline Pennell of Team Cee Lo, who stunned the coaches with her version of "The Way I Am" by Ingrid Michaelson.
Aguilera called her voice "effortlessly angelic," while Blake Shelton
offered even more vivid praise.
"Caroline makes me want to buy a cat and a pink blanket and light a little fire in the house with a cup of hot chocolate," he told her. "You are the best that there is this season."
Green agreed, and chose her over pop singer George Horga, Jr.
whipped through the knockout rounds in only two shows this week, with all the coaches finalizing their teams of five heading into the live rounds. With so many head-to-head performances, there was a whole lot happening behind the scenes that viewers didn't get to see.
