The five-person a cappella group Pentatonix holds candles in a cave for their Mary, Did You Know? video. The song (written by gospel singer/comedian Mark Lowry in 1985) is from their holiday album, That’s Christmas to Me.
Scott Hoying, Mitch Grassi, Kirstie Maldonado, Avi Kaplan and Kevin Olusola are the five vocalists who make up Pentatonix. In 2011, they met the day before the auditions for The Sing-Off on NBC. Together, they won. They tend to sing cover songs from a variety of artists including Lorde and Pharrell Williams. That’s Christmas to Me is their second full-length Christmas album.
