The fifth season of “The Voice” premiered on NBC Sept. 23 with the first blind auditions, and another first for the show started Monday, with live performances by the top 20 contenders that have made it this far, beyond the battle rounds.

The top 20 will now compete one-on-one, singing songs that they and their respective coaches have agreed upon. After the live performances, viewers get to vote on the artists who will stay to sing another day. On Tuesday, the artists from team Cee Lo and team Christina performed. Before the performances, Christina Aguilera joined band A Great Big World to perform their new single “Say Something.”

Team Cee Lo’s Amber Nicole singing “Wasting All These Tear,” by Cassadee Pope. Nicole was stolen in the knockout rounds by coach Cee Lo.

Coach Christina tells Nicole that she did her “own thing” with that song and she did great. Finally, Coach Cee Lo tells Nicole that she looked beautiful and that the song wasn’t a challenge for her because she did a great job.
