I'm a big fan of a cappella music.  Over the years there have been some terrific a cappella groups like the Nylons, the Blenders, Tonic Sol Fa and others who have put out some great Christmas music.   I'll add another name to the list: Pentatonix.  This Texas-based group formed in 2011 and became well-known after winning NBC's "The Sing Off".   They've already released two Christmas albums including their latest "That's Christmas To Me".

As you watch the video, you'll be amazed to know that they used absolutely no instruments on the song.   All the sounds produced are from their own voices.

You can also hear the song in our mix of holiday favorites on Y105...the Christmas station.  Find us on-the-air at 105.3 FM, online at y105fm.com or on your mobile device or tablet through the free Radio Pup app.
