"The Voice" continues tonight on NBC with the "Live Rounds" and all 12 contestants performing.  

The Swon Brothers did a beautiful piano and acoustic guitar arrangement of "Who's Gonna Fill Their Shoes" by George Jones.  

Judge/coach Adam Levine commented, "It was beautiful, I forgot it was a competition and was just enjoying the performance."

The Swon Brothers are the only duo left in the competition and Team Blake's only duo ever to make it into the live rounds.  

The contestants will find out if they advance to the next round tomorrow night. 

Judges this year on "The Voice" are Adam Levine, Blake Shelton, Shakira and Usher.
