Ep 10. The Knockouts Premiere

In the premiere of The Voice season 10's knockout rounds, the remaining contestants get their final chance to impress their coaches before the live shows. Each coach brings in a guest mentor to help guide their team through the knockout rounds. Adam Levine brings in Tori Kelly to help advise his contestants, while Christina Aguilera brings Patti LaBelle and Pharrell Williams brings in Diddy to assist their teams. Blake Shelton brings in country music star Gwen Stefani as his guest mentor.

During the knockout rounds, each contestant is paired up against another member of their team and given a song to perform. They must give it their all, as only one will move on to the live shows. The coach chooses the winner of each knockout, while the other coaches can steal the losing contestant if they choose to. Each coach has one steal to use during the knockout rounds, so they must be strategic in who they choose to steal.

The first knockout pairs two contestants from Team Adam - Owen Danoff and Ryan Quinn - against each other. They both deliver powerful performances, but Adam can only choose one to move on to the live shows. Gwen uses her steal to pick up Ryan, giving him a second chance in the competition.

Team Pharrell's Moushumi and Emily Keener go head to head in the next knockout. Moushumi delivers a stunning rendition of "Love Yourself" by Justin Bieber, while Emily chooses to sing "Big Yellow Taxi" by Joni Mitchell. Pharrell chooses to advance Emily to the live shows, but Christina and Adam both attempt to steal Moushumi. Moushumi ultimately chooses to join Team Christina.

Team Christina's Alisan Porter and Kristen Marie face off in the third knockout. Alisan performs "River" by Joni Mitchell, while Kristen chooses "Two Princes" by Spin Doctors. Christina ultimately chooses to advance Alisan to the live shows, but both Blake and Adam attempt to steal Kristen. Kristen chooses to join Team Blake.

The final knockout features Team Blake's Mary Sarah and Justin Whisnant. Mary Sarah chooses to sing "You Ain't Woman Enough (To Take My Man)" by Loretta Lynn, while Justin performs "Ain't Worth the Whiskey" by Cole Swindell. Blake decides to advance Mary Sarah to the live shows, but Adam attempts to steal Justin. Justin chooses to join Team Adam.

The knockout rounds continue next week, as more contestants battle it out for their chance to compete in the live shows.
