Andrea, who previously sang backup for Carrie Underwood, was up first. She channeled Faith Hill’s “Cry.” Lauren followed up her performance with a rousing cover of Alison Krauss’ hit, “When You Say Nothing At All.”

The video above, which features Lauren’s performance, shows the singer stepping inside the famous musical ring. And, boy does she give it her all! The 25-year-old beauty sports thigh-high black boots and a black dress, as she exudes so much emotion while singing the ballad. After Lauren’s rendition of “When You Say Nothing At All,” the panel of coaches gave their remarks on both of the hopefuls’ applaud-worthy performances.

“Andrea, the way that you delivered that song. It was very beautiful. There was a lot of power in your voice,” Alicia Keys said, “but sometimes I felt you were singing more than you were feeling. And, I thought that maybe Lauren was feeling even more than she was singing.”

Gwen Stefani added, “Lauren, I feel like that would be your record. But, if I were to choose, there’s something about Andrea for me, I just can’t believe that you’re not on the radio.”

“Andrea, you impress me,” Adam Levine added. “Lauren, you comfort me. I would go with Lauren.”

Blake, who was faced with the tough decision to choose between the two singers, admitted that he dreaded the moment. However, he chose to keep Lauren for his team.

“Alison Krauss is going to watch this thing and go, ‘Oh my gosh. That’s unbelievable!” he exclaimed.

Lauren will now advance to the live performance phase of the competition. Be sure to keep up with “The Voice” Monday and Tuesday nights on NBC.
