The final week of The Voice’s round 1 battles kicked off Monday showcasing the star power of some of Season 6’s teen artists.
Although she’s just 17, Bria Kelly once again closed the show with strength far beyond her years, taking on Janis Joplin’s “Piece of My Heart” for Team Usher in a closely matched battle with former NFL cheerleader and student Tess Boyer, 21, who surprised the coaches by stepping up her game.
The wholesome Kelly rocked it out hard with a sound that belied her sweet looks, earning praise all around. Usher chose Kelly, but Boyer of Glen Carbon, Ill., caught the eye of Blake Shelton who wasn’t about to let her leave the show just yet.
“I think Tess came out of nowhere on this thing,” Shelton said after Shakira called her voice “amazing.”
It was an emotional Glee-inspired sing-off between Provo, Utah, natives Madilyn Paige, 16, and Tanner James, 19, who attended the same school but who had never met until the show.
Singing Taylor Swift’s “Everything Has Changed,” the teens projected innocence and young love as Paige rose to the moment to feel the song’s heart and to project more as Usher had instructed her to do in rehearsals.
Jill Scott, Usher’s mentor this season, was rapt. “Her voice is like china, so it’s fragile. It can break,” Scott said of Paige, and urged the pair to “be starry-eyed, be in love, be an actor as well as a singer.”
“That was like watching Golden Retriever puppies frolic through fields of leaves through the sunset,” Adam Levine vamped. “Cute overload.”
