NBC has announced the two final groups, Traces and Timothy’s Gift, competing for a first-place prize of $50,000 on the two-hour special airing TONIGHT Wednesday, Dec. 17 at 8 p.m. EST of the popular musical competition series “The Sing-Off.”

Returning judges Jewel and Shawn Stockman will be joined by Fall Out Boy frontman Patrick Stump while Nick Lachey is once again set as host.

From New York, Traces are five spirit-filled divas who give gospel a modern twist with voices as big as their personalities. With their roots firmly entrenched in church, these women find time away from work to perform afternoon shows in front of appreciative and awe-filled audiences.

From Nashville, Timothy’s Gift is comprised of six women who met at church and often sing at maximum security prisons around the country to inspire inmates to have hope.

Also performing on the special will be season four “Sing-Off” champions Home Free, who will sing with Lachey and all three judges, as well as season three winner and hugely popular group Pentatonix.
