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
