On tonight's final performance episode of 'The Voice,' Vicci Martinez, the last woman standing on Cee Lo Green's team, performed the original song 'Afraid to Sleep.' The song was produced by Butch Walker, who is at the top of the pop game, having worked with the likes of Pink.

Martinez said she likes to start out soft and quiet and then launch into a powerful ending that punches people in the face. Well, this was the right song for such ambitions. The song may be titled 'Afraid to Sleep,' but Martinez's performance was nothing short of fearless. It was a power ballad which escalated through to the end. It was a solid and a little bit of a sleepy performance, so it was not her best or her boldest work. That was her rendition of Florence and the Machine's 'Dog Days Are Over' a few weeks back!

It's now up to America to make its decision about Martinez. Even if she doesn't win, she has Cee Lo in her corner and that's always a good thing.

Cee Lo was proud of her work, telling Martinez that he hoped he did a good job as her coach, while Adam Levine chimed in saying that he was fully invested in Martinez's performance.
