The Opera Avantasia heard in Metal sector of the best things I've ever heard. It took a long, until this masterpiece appeared in a worthy remake. The book packaging is classy and has a very detailed booklet, where are a lot of background information about the band, about Tobias Sammet, the lyrics, etc.. The complete story of the entire work can be read here, provided one understands English reasonably well. In addition, still a few music videos and interviews on the discs. To the music itself I need probably nothing to write, which is exalted to doubt.
Avantasia and metal fans come to this package barely past, especially since the price is very fair in my opinion is (individually would the two disks probably cost more).
