Some thing I discovered a few days ago, thanks to a colleague. It's a remake of Simon and Garfunkel's "The Sound Of Silence" by the Heavy Metal band "Disturbed". let me correct the last statement, it's an awesome remake of that song. I would go as far as to say it's better than the original. David Draiman has a powerful voice and does an amazing job of it. You can see the video here
Let me know what you think.
