Watch the 'Insane' Country Battle That Give Niall Goosebumps on 'The Voice' (Exclusive)

Tom Nitti, Dylan Carter

Tonight, is the penultimate Battle round on Season 24 of The Voice and Reba McEntire has saved two of her best country artists—Dylan Carter and Tom Nitti—to duet on Cody Johnson's "'Til You Can't."

Their pairing is a success, impressing all the coaches, and giving Niall Horan goosebumps.

“That was insane guys,” the former One Direction band member tells them. “Dylan, I could tell that song meant a lot to you. It’s written all over your face but you persevered singing-wise. You were so strong, so powerful and when the two of you started harmonizing together, it was electric. That's why the room was like, ‘Oh, we’ve got a Battle on our hands here.’ Tom, some serious gravel in there and you look so relaxed while you were doing it.”

Tom thanks Niall for the complement, but shares, “I appreciate that a lot because I'm shaking my boots.”

Niall was so taken by both of their performances that he told Reba he was not even going to try to call it, leaving the decision as to who moves on to Knockouts up to her.

It’s the same for Gwen Stefani. She says, “Dylan, the way that you were singing to Reba that was just such an adorable moment. Your voice is ridiculous. It's so beautiful. You're 20 years old and you're able to emote so well. Tom, I just kept getting blown away because to emote the way you did at the end, it just kept building and building. I'm going to let the queen decide this one.”

Reba isn’t happy with the fact that neither of her fellow coaches is helping her make this difficult decision. But maybe John Legend will.

“Tom, at the beginning, I felt like maybe he’s hiding behind the guitar a little bit, and then you showed us this whole other side of you,” John says. “You turned on the heat and it just felt like a revelation, like, ‘Oh, there's Tom.’ And Dylan, you were just consistently outstanding the entire time. Your voice is wonderful. You were like spiritually in tune with what you were singing.”

Again, no help from a fellow coach, but then it’s Reba’s turn to critique her artists.

“I thought [the Battle] was absolutely marvelous,” she says. “Even though your style of singing is so different, it complemented each other. It was just magical to me.”

Then Reba turns to Niall and says, “Remember when you were in a competition and then somebody put all you guys together? I can see a really good duo right here.”

Niall jumps in saying, “Dylan even looks a little bit like me.”

Reba adds, “I love you both. You're both great singers. I don't know what else to say.”
