This Jennifer Hudson and Pentatonix duet will give you chills

The second annual “A Very Pentatonix Christmas” special is airing on Nov. 27, but NBC is already teasing the musical greatness that will soon be coming to your television screen. Based on the clip they released of Pentatonix and Jennifer Hudson singing “How Great Thou Art”—you’ll want to tune in!

The Pentatonix a cappella group won “The Sing Off” back in 2011, and they’ve been making incredible music using only their combined voices ever since. But when they do decide to team up with other artists, the results are amazing, and this video proves it.

To sing “How Great Thou Art,” they collaborated with none other than powerhouse vocalist Jennifer Hudson, and the performance is too good to describe with words. You have to hear it to believe it:

Their voices come together seamlessly, and when Hudson is singing on her own, it’s truly miraculous. She hits those high notes perfectly and, ultimately, delivers one killer performance. Naturally, people can’t stop talking about this duet online. One person called the collaboration “phenomenal” on Twitter:

If you weren’t expecting to become emotional upon hearing this song, you’ve been warned.

This is just one of many incredible performances that the NBC TV special has in store. Kermit the Frog, Jay Leno and even more celebrities are also scheduled to make appearances.

The show airs at 10/9 central on Nov. 27, so make sure you’re in front of the TV to catch these incredible musical renditions.

In case you’re dying to let the holiday music listening party begin—you’re in luck! You don’t have to wait until Nov. 27 to start listening to the Pentatonix’s take on Christmas classics. Here’s their version of “Away In A Manger” to get things started:

Follow that up with “Little Drummer Boy.”

There’s even more where that came from on their official YouTube channel.

Now you’re well on your way to getting in the Christmas spirit. Tune in on Nov. 27 for all of the Christmas joy you can handle!
