"For the first time in Voice history," host Carson Daly exclaimed, the bottom two singers were eliminated, regardless of whose team they were on. That means no more saves by the coaches.
"I think (the new rule) sucks, Carson," said Adam Levine, a self-proclaimed control freak, quickly adding, "I love you, America!" (He proceeded to use the phrase "double-edged sword" incorrectly.)
Next came a mix of performances, a video clip and announcements of singers who made it through.
First on stage: coaches! Premiering her single Make the World Move and reminding everyone how a vocal run is done, Christina Aguilera got out of her red chair to sing. In thigh-high white boots and a curly pink Afro, she performed with CeeLo, who's featured on the song.
Next was a prerecorded segment about how great the singers' lives are now that they are on The Voice: People recognize them in the bathroom. One important thing learned from the video: Team Christina's Dez Duron is single.
And some contestants were sent through. First two: Team Adam's Bryan Keith and Team Christina's Sylvia Yacoub.
Another performance: Jason Aldean stopped by to sing The Only Way I Know, with Keith and Dez chiming in.
Aldean told Christina Milian in the "skybox," "Usually I do this song with Luke Bryan and Eric Church," so props to Dez and Bryan. He then shared advice: "As an artist, you gotta be yourself," and a fun tidbit: "Blake (Shelton) used to have one of the gnarliest mullets" in 2006.
And back to the eliminations. Two more artists were safe: Team CeeLo's Nicholas David and Team Christina's Dez Duron.
Next, CeeLo Green was onstage in Saturday Night Fever garb, singing Staying Alive with his team. And more singers moving ahead: Team CeeLo's Trevin Hunte and Team Blake's Cassadee Pope.
And, back in performance mode, Blake and his team sang Life Is a Highway.
Don't worry, more saves: Team Blake's Terry McDermott and Team Adam's Amanda Brown are moving on.
Four artists remained: Team CeeLo's Cody Belew, Team Adam's Melanie Martinez, Team Christina's Adriana Louise and Team Blake's Michaela Paige.
Saved: Cody and Melanie. That means Team Blake's Michaela and Team Christina's Adriana were sent home, while coaches Adam and CeeLo still have all three of their singers.
Some parting words: Michaela tearfully said, "Follow your dreams and go after what you want," and a choked-up Adriana called coach Christina "everything that I could've wished for and more."
Next Monday (8 ET/PT), the Top 10 sing for your votes.
