The Voice continued the live rounds on Monday night, with the 10 remaining artists taking the stage for solo performances. Adam Levine , Blake Shelton , Shakira and Usher were there to offer their two cents.
Here's what happened during the two-hour show:
Adam brought in rock legend Graham Nash to mentor Team Adam's Kat Perkins as she worked up Fleetwood Mac 's "Landslide." Graham warned her to be careful of the low notes. Blake enjoyed seeing Kat's softer side, and Adam called her a "blissfully perfect, amazing singer."
Team Shakira's Tess Boyer almost went home last week, so the stakes were high as she sang "Ain't It Fun" by Paramore . Blake called the performance "pitch perfect," and Usher felt she was comfortable moving onstage. Shakira said Tess nailed it.
Audra McLaughlin from Team Blake took on Reba McEntire 's vocally-challenging country hit, "You Lie," but she flubbed the lyrics. Usher said this performance took Audra to another plateau. Shakira predicted Audra would make the top five this week.
Team Usher's Josh Kaufman showed off his vocal range singing Kenny Loggins ' "This Is It." Shakira said soulful songs were Josh's "sweet spot." Blake said Josh's performance sounded just like a highly-produced record.
Adam protégé Christina Grimmie turned Drake 's "Hold On, We're Going Home" into a piano power ballad. Blake said Christina went from being a singer to an artist with this performance. Adam praised Christina's artistry and said she gave him goose bumps.
Jake Worthington from Team Blake sang his hero and fellow Texan George Strait 's hit, "Run." Shakira and Usher were proud of Jake for coming so far in his time on the show. Blake called it a "solid, great performance" that would make George Strait proud.
Team Usher's Bria Kelly let her emotional guard down singing Avril Lavigne 's "I'm With You." Shakira said this song allowed Bria to challenge herself. Adam didn't feel Bria really connected with the song. Usher thought Bria grew with this performance.
Delvin Choice of Team Adam went with Gary Clark Jr. 's "Bright Lights." Blake said Delvin has "power and passion," and Usher said Delvin brings out the gospel in any song. Adam was very happy with Delvin's performance and said he shocked the audience with a false ending.
Kristen Merlin broke out of her country mold singing "Let Her Go" by Passenger with guidance from her coach, Shakira. Blake said it was his favorite performance from her. Shakira was so proud of how far Kristen has come.
Team Blake's Sisaundra Lewis rocked out with Steve Perry 's "Oh Sherrie" to close out the night. Usher said she was incredible, and Adam said Sisaundra blew the roof off the studio.
As the show aired on the East Coast, Blake needled Adam by tweeting what he claimed to be Adam's cellphone number, with Carson Daly retweeting it. Whether it's actually Adam's number is unclear.
British band Rixton made their U.S. television debut at the top of the show singing their hit, "Me and My Broken Heart."
Two contestants will go home and Usher and Shakira will perform with their respective teams on The Voice Tuesday night at 8 ET on NBC.
