The words "heavy metal monk" appear in the story. The said monk, sixty-two years of age, makes the devil sign in the video while singing growl-y metal vocals. So if you don't want to burn in hell while being poked on your sides by Gibson Flying-Vs, check out this awesomely cool story.
I hope that when I am sixty-two, I am still as inspired and moved by music - by any and every form of music - as Brother Cesare. And that my mind is still open to accepting new ideas.
