Watch Riley Green Make 'Tough' Decision After Two 'Voice' Contestants Cover Duet With Ella Langley

Riley Green said two of his artists "crushed" their performance of his song on The Voice.

Joe Henley, 19, of Alabama, took the stage with Kenna Elpers, 23, of Indiana, during the Battles this week. The two artists delivered a rendition of "Don't Mind If I Do," the title track of Green's third studio record featuring fellow country star, Ella Langley.

"Boy, you could not be more different," Kelly Clarkson said after the stunning performances. "Kenna, you have this, like, Alison Krauss, beautiful sweetness to your voice and that vibrato, it's, like, so quick, like a beautiful butterfly. …Joe, I wanted you in the blinds because your voice - I call it the Randy Travis effect. You open your mouth and it doesn't matter what you're singing. Your voice has such a depth to it. It just commands attention. That's something you can't teach. That's just God given, you know?

Coaches Adam Levine and Queen Latifah also praised the rendition of "Don't Mind If I Do." Host Carson Daly asked Green for his thoughts, and prompted him to decide the winner of the battle.

"Kenna, I don't have a problem saying this, and I think Joe would agree with me. I don't think he could do what he's doing here if it wasn't for you," Green said. "I mean, I know how hard you've worked. And Joe, the reason everybody was so excited about your voice is because you've got something that is completely God given. The fact that you got that much better for this performance, I'm really proud of you for doing that.

"It's extremely tough because I'm such a big fan of both of y'all, and I really want both of y'all on my team," Green continued. "And a part of me is kicking myself for making this pairing, even though I'm glad I got to hear y'all sing the song together."
