'The Voice' 2013 Recap: Usher, Blake Shelton Cut Teams To Four In Knockout Round, Rosters Set For Live Playoffs

The knockout rounds continued Tuesday night on "The Voice" as Usher and Blake Shelton whittled down their teams to four contestants apiece.

In the knockout round, each coach picks two of his or her team members to sing against each another. The performers must choose their own songs and no steals or saves can be used as in previous rounds. Half of the eight contestants on each team are eliminated and the remaining four advance to the live playoff round.

Savannah Berry faced Justin Rivers first for Team Blake. Savannah peformed Justin Bieber's "As Long As You Love Me" while Justin went with Miley Cyrus' "The Climb." Blake chose Justin to advance despite the fact that he claimed the contestant took a risk performing a woman's song.

Josiah Hawley faced Jess Kellner next for Team Usher. The former sang Amy Winehouse's "Back To Black" and Jess countered with James Morrison's "You Give Me Something" in honor of her mother. Usher selected Josiah after he praised the grit in his performance.

Holly Tucker took on Luke Edgemon in the next faceoff. Holly went with Tim McGraw's "Live Like You Were Dying" and Luke performed Katy Perry's "Teenage Dream" in an R&B style. Blake picked Holly to advance.

Audrey Karrasch went up against Michelle Chamuel for Usher, who tried to shake things up by having the two jump rope and do push-ups during rehearsals. Audrey sang Lil' Wayne's "How To Love" and Michelle performed Pink's "Raise Your Glass." Usher picks Michelle for his final four.

For Team Blake, Danielle Bradbery faced Taylor Beckham next. Danielle stuck to her country roots and chose Carrie Underwood's "Jesus Take The Wheel" while Taylor picked Rihanna's "Russian Roulette." Blake stayed true to country, too, and picked Danielle to advance.

C. Perkins chose Chris Brown's "She Ain't You" to go up against Vedo's rendition of "Everything I Do (I Do It For You)" by Bryan Adams as the two faced off for a spot on Team Usher's final four. Vedo got the bigger crowd reaction and the nod from Usher.

Grace Askew faced The Swon Brothers for the final spot on Team Blake. Grace picked Tina Turner's "I Can't Stand The Rain" and the brothers selected Dobie Gray's "Drift Away." The Swon Brothers impressed Blake and earned the final spot in his final four.

Cathia squared off with Ryan Innes in the final performance of the night. Cathia, who normally picked non-English songs throughout Season 4, chose Kelly Clarkson's "Mr. Know It All" while Ryan opted for Gavin DeGraw's "I Don't Want To Be." Usher picks Cathia to round out his final four.

So the final roster for Team Blake is Justin, Holly, Danielle and The Swon Brothers. Team Usher is Josiah, Michelle, Vedo and Cathia.
