Since this just popped up, I saw Disturbed this weekend and they nailed it. Best show I have been too. David's version of the Sound of Silence is even better live, but then I like his version better than Simon and Garfunkel's too.
Nobody does it better or ever will, then Simon and Garfunkel IMHO. There are songs which become instant classics the minute the track is recorded. The Sounds of Silence is one of those gems that will be untouchable until the end of time.
