"The Voice": Top 8 deliver memorable Memorial Day performances

The Memorial Day edition of "The Voice" kicked off Monday night with coach Blake Shelton (whom Carson Daly introduced as a "rarely sober national treasure") performing his hit "Boys 'Round Here," before the eight remaining singers pulled out all the stops on stage.

Two of those contestants will be sent home during Tuesday's results show. Read on to see how they fared:

Team Adam:

Judith Hill, sporting a mohawk ponytail and feathered cape, gave her take on will.i.am and Justin Bieber's "#thatPOWER." This was her first cover of a current radio song, and the coaches loved it. "This is not a contestant on 'The Voice'; this is an artist performing a song, just like all of us [coaches] do," Adam Levine said.

Sarah Simmons was tasked with singing Gotye's "Somebody That I Used to Know," but it seemed like she struggled throughout her performance. Usher praised her for showing a different texture in her voice, while Shakira simply called it "interesting." Levine defended Simmons, saying no one on "The Voice" has done this song right until now.

Amber Carrington was given a doubly difficult task: Not only to sing an Adele song, but her James Bond theme "Skyfall." She met the challenge and then some, delivering a forceful and dramatic performance. "I think you just took the diva powerhouse vocal of the night," Shelton told her.

Team Blake:

Holly Tucker delivered a confident rendition of The Band Perry's "Done" that her coach said left the song "begging for mercy." "There were big notes in this song, and you hit them and took them up to another level," added Usher.

The Swon Brothers sang a bluegrass-tinged version of the Eagles' "Seven Bridges Road" with a starry sky and live campfire onstage. "Those classic Eagles harmonies really suited your voices," Shakira said. Levine offered a few minor criticisms, but still agreed that the duo was "amazing."

Danielle Bradbery sang The Judds' "Grandpa (Tell Me 'Bout the Good Old Days)" at her coach's request. Though she wasn't familiar with the song beforehand, she delivered a performance that was warm and sweet. Usher called her a prodigy, Shakira noted her "star quality," and Levine added, "Regardless of what happens on the show, you are so important because you're a country music artist that's waiting to be born. It's staggering."

Team Shakira:

Sasha Allen took on "Without You," by David Guetta and Usher, who offered her his congratulations. Shelton called her performance "fun," and added, "I think you bought Shakira another week on this show for sure."

Team Usher:

Michelle Chamuel delivered a dynamic performance of Bruno Mars' "Grenade" that Shakira called "spectacular." Levine hailed her as "exciting" and Usher praised: "You put in the work. People can identify with an incredible spirit. You represent true inner beauty."
