Although I do know that four band's albums (Wishmaster, Once, Dark Passion Play, and this one), I must say I am very satisfied with this album. We feel that Nightwish was renewed by changing singer, and although this concept album is a gamble, it is for me successful. The album has its own identity and voice of the singer is well-suited to pieces ... and it's very pleasant to have some entirely instrumental pieces, it reinforces the unique atmosphere of the album. Of course, it is far from Wishmaster, but good bands evolve and renew themselves.
