STAGE TUBE: THE VOICE Contestants Compete in First Battle Round

On last night's episode of the NBC singing competition THE VOICE, The "battle rounds" began and the coaches enlisted the help of music industry professionals to offer their knowledge and skill as advisers. Christina Aguilera teamed up with Jewel and Lionel Richie, Adam Levine with Alanis Morissette and Robin Thicke, Cee Lo Green with Kenny "Babyface" Edmonds and Ne-Yo, and Blake Shelton with Kelly Clarkson and Miranda Lambert.

In this phase the coaches pit two of their own team members against each other in a dueling duet. After the vocal face-off, each coach had to choose which vocalist from their team was the strongest and advance them to the live shows. 

Christina Aguilera decided to pit operatic singer Chris Mann against smooth-singing Monique Benabou in a performance of 'The Power of Love'. To see the competition, click below!
