Known to have won NBC's The Sing-Off Season 4, they performed "Life Is a Highway", a song written by Tom Cochrane in 1991.

Giving the song a different twist by rendering an accapella version, they nailed the song with their catchy beat wowing the crowd.

Using their voice only without using any musical instruments, they managed to deliver the song as if it was with an accompaniment.

Check out the video and see for your self how they nailed it.

They know how to entertain a crowd.
