The Knockout round came to a close on NBC's The Voice season 18, which built up to a four-way Knockout between the saved artists from the Battle Round. Coaches Kelly Clarkson and Nick Jonas still had steals to use at the top of the night, but Blake Shelton and John Legend were out of steals for the round. James Taylor continued to serve as celebrity mentor.
The night started out strong with Knockout performances from two of Team Legend’s four-chair turns: Thunderstorm Artis and Mandi Castillo. It seemed immediately clear that this would result in an early steal. Artis sang Legend’s own “Preach,” while Castillo sang “Stand by Me,” and both delivered original, layered performances that reiterated how strong of a coach Legend is. The emotions and vocals were captivating, and Legend was left with a tough choice. He decided to keep Castillo, which was a little surprising, but Jonas swooped in to steal Artis, keeping both in the competition. It was a big win for Team Nick.
Jonas faced a pretty easy decision with his first Knockout of the night. Jon Mullins sang “Thinking Out Loud” by Ed Sheeran, and Arei Moon sang “You Don’t Know My Name” by Alicia Keys. Jonas worked with Mullins to come up with a strong arrangement, but Moon simply gave the more dynamic and memorable performance. Jonas kept Moon and Mullins was eliminated.
