Christmas music has been rearranged for nearly every conceivable genre, including grittier ones like symphonic rock and heavy metal. “Carol of the Bells” and “God Rest Ye Merry Gentlemen” are popular choices for edgy arrangements, but one song manages to be epic without dubstep wubs or electric guitars.

“Fum Fum Fum,” as performed by Mannheim Steamroller, is a fusion of rock and Renaissance styles. It’s pretty tame for the first minute, and then heats up with a woodwind (I’m guessing a tin whistle) carrying the melody over light synths and some solid percussion. This is my all-time favorite instrumental Christmas tune.

Christmas is nearly here, guys. Prepare yourselves.
