Watch This Festive Take On Slayer's Most Evil Song

YouTuber Andy Rehfeldt is on a roll. The mash-up merchant has been responsible for pairing Guns N' Roses' Welcome To The Jungle with the Benny Hill theme, and transforming Black Sabbath's War Pigs into a smooth jazz track.

His latest offering pairs Slayer's most notorious song Angel Of Death with, um, Sleigh Ride, as performed by the United States Navy Band.

"This nauseating tune makes me want to break things, so this one works as therapy for me," says Rehfeldt.

We think he's talking about the Christmas song.

Anyway, here's a particularly twisted festive offering.

Here's the original for comparison.
