Now, Hollens is back to amaze us with his incredible voice talents in this a cappella version of "I See Fire," which was written by Ed Sheeran for "The Hobbit: The Desolation of Smaug."
"'I See Fire', 'Misty Mountains,' and all of my songs are recorded using only the human voice," Hollens told The Huffington Post in an email. "This song was created with 98 tracks of my voice as well as stomps, claps, and snaps!"
"The Hobbit" hits theaters on Dec. 13, and we can't think of a better way to get excited for the movie than to see Peter Hollens incredible rendition of "I See Fire."
