Top 8 of "The Voice" were neck and neck in a fight for the top 6 spots on Monday night, May 27. Beforehand, the Memorial Day episode was kicked off by Blake Shelton, whom host Carson Daly described as a "rarely sober national treasure," and Gwen Sebastian with a performance of Shelton's hit "Boys 'Round Here".

Team Adam Levine was first up, sending Judith Hill on stage to sing "#thatPOWER" by will.i.am featuring Justin Bieber. Shakira praised her for doing an incredible job in tackling the risky song. Sarah Simmons was next with her cover of Gotye's "Somebody That I Used to Know", leaving Shelton impressed by her soft and raspy voice. Last protege Amber Carrington brought down the house with a strong performance of Adele's "Skyfall".

As the only one left in Team Usher, Michelle Chamuel, took the stage, she proved herself to be a strong rival for the rest contestants. Chamuel showcased an amazing vocal in her version of Bruno Mars' 2010 hit "Grenade". Levine gushed that it was one of the best of the night.

Another single fighter from Team Shakira also showed off an incredible singing on stage. Sasha Allen took a risk by covering Usher and David Guetta's "Without You" and delivered a soulful rendition which successfully wowed the judges, including Usher as the original singer.

Team Shelton then attempted to heat up the show with an equally strong vocal from each country talent the "Austin" hitmaker had. First up was Holly Tucker, whose vocal took The Band Perry's "Done" to another level as said by Usher. The Swon Brothers also earned judges' nods with The Eagles' "Seven Bridges Road", dedicated to those affected by the Oklahoma tornado tragedy.

Shelton's last protege Danielle Bradbery shone through her pure voice shown in her performance of The Judds' "Grandpa (Tell Me 'Bout the Good Old Days)". "It's staggering," praised Levine.
