A quantum leap!

Worked her voice smooth and polished a little artificial at the last time, here is now all her pristine vocal power that impressed over and over again every time you listen.
Convince the songs individually as well as a total composition, the balance between quiet ballads (eg the catchy "I feel immortal" or the vocally very classic "Rivers of Lust") and harder tracks ("In for a Kill" -with a voice is sharp as a scalpel, or the euphoric "Falling Awake") very balanced.

All in all, it seems finally to have found their own style, quieter than the Nightwish olden times (and I hear the comparisons, already on), and much more based on classical singing, but with an incredible creativity and harmony diversity, in which you can always discover something new.

The Limited Deluxe Edition I have already recommended because, a melodic ballad which belongs in my eyes with the best songs of the album alone of the bonus tracks "Naiad".

In my view, "What Lies Beneath" complete success and highly recommended.
