You might wonder why no one’s decided to metalize the theme song of The Walking Dead before. Actually, they have. What about a metal version of Michael Jackson’s “Thriller?” Actually, Testament’s Chuck Billy did that last year. However, no one’s thought of combining them until now. The CloudRunner, a multi-person collaborative act, have teamed up with different musicians from around the world to help out with their cover(s). It looks like it took a lot of work for it to come together, and it also looks like everyone had a lot of fun making it. You can grab an MP3 version of it here.
