You are right Frank. I had a chance to see them and not knowing what to expect I was BLOWN AWAY! I am also a huge hard rock/heavy metal fan and the show was just unreal. Anyone who has a chance to go will not be dissapointed.
The youtube videos are cool but really don't do them any justice. When you are there and can feel the music it is entirely different. If you like music you will really like seeing one of these shows.
