From the Killers to Weezer, rock's biggest acts are in the holiday spirit. Today, Brandon Curtis of psych-rock trio Secret Machines unveils the strangest rendition of "Silent Night" we've ever heard.

With oscillating computer-generated noise, sparse piano chords, and ghostly backing vocals courtesy of New York songstress Tamaryn, Curtis' interpretation of the classic track stays true to the song's title -- dark, yet eerily quiet.
