Pentatonix Send a New Voice Message

They made a very tuneful kind of history in 2015—as the first vocal-only group ever to score a No. 1 album—and now this talented quintet is on a mission to raise everyone’s a cappella awareness.

The members of Pentatonix make that mission pretty clear on “Sing,” our Song of the Month for January. Check out the video below. (You can also hear the audio portion of this clip in our Hear the Music playlist.)

Need more Pentatonix? Here’s the video for their Grammy-winning “Daft Punk” medley.

Last but not least, here’s the powerful performance of Florence and the Machine’s “Dog Days Are Over” that lifted Pentatonix into the Season 3 final round of NBC’s The Sing-Off in 2011. (They won that round too.)
