The Shields Brothers say they hope to "punch America in the face with rock 'n' roll.' On Monday night, all four coaches on 'The Voice' escaped their "chaotic" audition without black eyes or busted lips, and Cee Lo Green found his newest team members. Green loved their rendition of Billy Idol's "Dancing With Myself.'

Tristan and Rory Shields live on a farm with their mom and dad, "and if we won 'The Voice' we would no longer have to live on a farm with our parents," they said before they began singing. Dad was on hand, and he seemed to agree that the kids needed to find their first job. When Green hit his plunger, it wasn't clear if he was more excited for his sons or himself.

"It was chaos a little bit listening to it," Blake Shelton said. All four mentors were surprised to hear a second voice join in early in the frantic performance. One brother was clean cut in a purple leather jacket while the other kept a blonde bird's nest above his shoulders. There's no doubting they packed every ounce of energy they could conjure into the showcase.

"It was great energy, really, really fun," Christina Aguilera said. While only one of the four were convinced enough to take a chance on the pair from Rixeyville, Va. that's good enough to put them through to the battle rounds, which begin next week.
