Watch a Sneak Peek of 'The Voice' Knockout Between Team Kelly Clarkson's Holly Brand and Rachel Christine

The Voice Knockout Rounds for season 23 continue on Monday night, but first, here’s a sneak peek of the Knockout between Team Kelly Clarkson’s Holly Brand and Rachel Christine.

For her song choice, Holly selects Patsy Cline’s “Blue Moon of Kentucky” and Rachel sings Fleetwood Mac’s “Rhiannon.” Which one will make it through to the Live Playoffs?

“My team is so good!” Kelly said when the two women were done performing.

But Blake got the first critique. He said, “You both did great. What’s not awesome is the Knockout Rounds. They suck. Holly, you have a great yodel and have awesome control of it. Rachel, I felt like after what Holly came out here and did, I was like, ‘Now she’s going to do "Rihannon"? What?' But you did an awesome job. You sang the crap out of it, and found some notes that were different from the record. Nothing but an awesome performance.”

“Rachel, you did a great job of coming back on my radar,” Chance the Rapper said. “I had never heard of the song before. I have heard of Rihanna. Great performance, Rachel. Holly, you completely blew me away. You started off a cappella and you have to have perfect pitch to start like that and stay in it throughout the song. The whistle note at the end was a crazy cherry on top. You had already killed the whole thing. Cool moment.”

Next was Niall Horan, “‘Rhiannon’ is one of my favorite songs of all time and your ability to change things up is really impressive. You smashed it out of the park. It’s bulletproof. It was really good. Holly, I’ve been a fan since day one. I think we got to see what Holly Brand is about, even down to the outfit and the sparkly boots … and the puffy sleeves. I would look like Rob Gronkowski if I wore them! That whistle note at the end … people don’t know how hard it is to do. I am leaning toward Holly just for the uniqueness of things.”

Then it was time for their coach Kelly to rate her team.

“You both picked perfect songs,” she said. “Holly, doing the whistle note and how you incorporated into a Patsy Cline hit, that’s incredible. You were like, ‘I don’t know if I can belt at one point,’ and you did it and it was killer. Thank you for doing that and trusting yourself. Rachel, you remind me so much of me when I was younger. To come after someone singing whistle notes…and the crowd is like, ‘Ahhh,’ and you have to start out so mysterious and all Stevie Nicks, I don’t know that anyone sitting here [referring to the other coaches] could do that and not feel a little shaken. You are just an incredibly gifted singer.”

So, when all is said and done, who does Kelly pick to go through to the Playoffs?

Tune in Monday night at 8 p.m. ET/PT on NBC to find out.
