Pentatonix has been a wildly popular a cappella group, gaining notoriety after winning the singing-competition show "The Sing-Off" back in 2011. The quintet currently has over 14 million subscribers.
Much of Pentatonix's success is due to its modern takes on Christmas classics. Some of the group's most popular videos have been holiday-themed.
Pentatonix released its new songs "Away in a Manger" and "Deck the Halls" in October as part of a new album, "A Pentatonix Christmas." The full album can be found below.
The album featured bass vocalist Matt Sallee in place of previous bass Avi Kaplan.
Kaplan left the group in May due to personal reasons. He explained that he could "no longer continue at this pace" and expressed desire to spend more time with friends and family. Kaplan's farewell video was posted on the Pentatonix Facebook page.
Another member of the group, Kirstin Maldonado, is reportedly working on her solo debut, according to Hugh McIntyre, a Forbes contributor. Other band members also are beginning attempts to pursue personal projects.
In case we may never see the original band back together, here's a list of the group's top 12 most-viewed Christmas videos on YouTube.
