The Voice concluded its eighth-season "Battle Round," advancing four artists to the next phase of the competition, during Tuesday night's broadcast on NBC.

On Night 4 of the Battles, The Voice coaches Adam Levine, Christina Aguilera, Blake Shelton and Pharrell Williams had to narrow down their teams by matching up two artists at a time to perform the same song in the hope of outdoing one another.

Each coach has the opportunity to steal two artists who lose their respective battles during this round. At this point, Pharrell was the only coach left with a "Steal" remaining.

Adam's advisor is Ellie Goulding, Christina teamed up with Nick Jonas, Blake is working with Meghan Trainor, and Pharrell's advisor is Lionel Richie.

Christina paired up Jeremy Gaynor and Rob Taylor to sing "Animals." She declared Rob the winner.

Pharrell required Noelle Bybee to face off against Sawyer Fredericks with the song "Have You Ever Seen the Rain." Sawyer won.

Blake matched Corey Kent White with Jacob Rummell and had them perform "I Want Crazy." Corey won the Battle.

However, Pharrell decided to use his last "Save" on Jacob, ultimately keeping him in the competition.

Next week, the "Knockout Round" begins.

In this round, each coach will pit two of its team members against one another -- just like in the Battles. But this time around, the singers will take the stage one at a time and sing different songs. Each person is allowed to pick his or her own song, showing everyone what type of artist they are or would like to be.

Each coach will only be afforded only one "Steal" during the Knockouts.

In the closing credits of Tuesday night's episode, it was revealed the frontman of Fun, Nate Ruess, will serve as Season 8's universal mentor. Last season, Taylor Swift took on this role. Nate will be allowed to guide and advise every contestant no matter which team he or she is on.
