My gift to you, my fabulous reader. The title of this post may be a bit of a misnomer, I admit. While these wallpapers are not directly metal-related, they are all the product of a wonderful YouTuber by the name of Tillsilence. He creates charming symphonic covers of metal tunes along with a background picture for each. These images just happen to make for marvellous wallpapers. I'm out of flowery adjectives so check him out here. Additionally, I've posted some more wallpapers after the break.
And as a thank you for reading on, I present you with a kickass Dethklok wallpaper.
