Artist of the Week: Pentatonix

The five-member a cappella group has scored their second chart-topping album with 'A Pentatonix Christmas'.

Pentatonix has become the new kings (and queen) of Christmas music. The five-member a cappella group recently scored their second No. 1 album on the Billboard 200 chart with their latest album "A Pentatonix Christmas".

PTX's fifth studio album peaked the chart after getting 206,000 total copies sold in its ninth week, including 185,000 in traditional album sales, according to Nielsen Music. The record also became the first holiday album to land at No. 1 on the Billboard 200 chart in five years, since Michael Buble's "Christmas", and earned the largest sales week for a holiday album in two years, since the group's previous holiday record "That's Christmas to Me".

Formed in 2011, Pentatonix came to prominence after winning the third season of NBC's "The Sing-Off". After receiving $200,000 and a recording contract with Sony Music, the group later formed their own YouTube channel, distributing its music through Madison Gate Records, a label owned by Sony Pictures.

PTX's YouTube channel is currently the 13th most-subscribed music video channel with over 11.5 million subscribers and 1.80 billion views.
