Check out this viral video of a Slayer’s fan computerized christmas light show on his house.

Apparently, the guy who created this amazing display is the father of the YouTube account holder, hence the incongruous mix of Bieber and Slayer therein.

From the metal dad’s replies to viewer comments on the video:

“Slayer!! I have been a fan for over 20 years and this took me a long time to do.watching it in person was awesome. Dedicated to Slayer and all the fans!!!!!"
