There's no doubt that The Piano Guys are beyond popular. Their talented performances are known world-wide and now they're teaming up with another powerhouse for a special Christmas number.

Just watch as these gentlemen perform with Lexi Walker for a stunning mashup of 'O Holy Night ' and 'Ave Maria.' This classic hymn is one of those songs that you just have to listen to at least once every holiday season. It was truly a glorious night when Jesus was born. The angels rejoiced and the whole world received their King. God granted us eternal salvation when He sent His Son to die for our sins.

This is truly a moment to celebrate and rejoice. And this holiest of nights is praised perfectly through this song. I'm so glad that this talented ensemble decided to perform this special song. All of those instruments and Lexi's vocal combine for the most incredible sound. Who else loves this performance?
