A hush always fills the room whenever Pentatonix gathers.

What they fill the silence with is enough to leave you stunned for minutes after it's over.

Taking on music giants like John Lennon, Queen, Dolly Parton, and amazing Christmas classics like God Rest Ye Merry Gentleman, Mary Did You Know, O Come, All Ye Faithful and Up on the Housetop it's no surprise that they would take on the King of Rock n' Roll next.

The unique spin on they put on an Elvis classic, it's enough to send chills down your spine.  

With just the sound of their voices working in harmony, the silence in between notes is haunting and beautiful.

These 5 vocalists just sound so perfect together.

I have never heard an Elvis song sung like this before. Video on the next page.

Can't Help Falling in Love is arguably one of the most well-known Elvis song of all time.

Elvis originally released the song in 1961 and it was an instant hit! The album was a certified platinum and sold over 1 million copies in the United States alone.

The song has since been featured in major motion pictures including Lilo & Stitch, Coyote Ugly and Overboard.
