“Enter Sandman” is one of the greatest songs from Metallica. Chances are you’ve heard it before, but I bet this is the first time you’ll hear this version. What made me say this? All the video and audio in this video is in reverse: every instrument, the vocals and even the guitar solo. And it makes for an outstanding performance. I’m not going to lie, it can be confusing, but you should definitely check this performance out. And if you enjoyed it, the only thing left to do is to share it with all of your friends and family.
