If you are a fan of this band you really should pick up the Limited Edition cd version as it has 4 live dvd's and 1 music video so all 6 shows can be watched in their entirety. It is worth every penny, I would buy anything they put out! All these Dvds include interviews with members past and present so it's definitely money well spent.

Ex Output:
Good Review

This was very disturbing reading. Nothing like the authors other novels so far. Not sure what she was thinking? Don't recommend at all.

I was reading reviews regarding the color of what you see from viewing screen. This is what they have to say about this picture: "It appears blue due to too many lighting." In other words for someone who enjoys bright lights, this picture has them in a cloud all over it. Other than that it is an okay picture, so far. Still trying to figure out how to use it, but hope with time, it will become easier.
