@Zare I don't think the fantasy element has disappeared.
I for one exprienced and happen to like the Tarja era, and especially
Oceanborn,
Wishmaster,
Century Child. But
Once was also pretty OK as well. Ghost Love Score (and the track you mentioned, Dark Chest of Wonders) was amazing, especially live! The
melodies and atmosphere in that era were outstanding.
The debut aside, the older albums had a strong Stratovarius influence. And I like Tarja's voice. When it comes to her operatic style, I think she does that type of Nightwish material a tiny bit better than Floor. And when it comes to singing in softer, more fragile parts, I also prefer Tarja.
Floor is more allround, and more powerful midrange. I prefer her as a singer in general, but in Nightwish I must admit that I prefer Tarja on the songs she did. She made a lot of impact, and it can clearly be heard that the songs were written for her. A perfect match.
IMO, it doesn't get much better than Ghost Love Score, but when we go back a bit further in time, there's this:
Check Stargazer and especially
Gethsemane (proggy and haunting later on, and when you think it can't get much better, then that last solo enters. Superb build-up.
). Passion and the Opera kicks ass as well. Try to be patient with the power metallish elements. Then you'll be rewarded when other instrumental midpieces arrive. Nightwish added a lot of their own.
However there are two things why I'm going to get this record - they seem to have taken a more prog-based route lately,
Not sure what you mean by that (perhaps that new dude with his fluty instrument?) but the songs are not more proggy in a sense that you can digest more out of recent songs than earlier work. Older Nightwish also had long, epic songs with lots of changes. And the ballads with Tarja are among the best in the whole metal genre.
This is a great song, starting out as ballad, with moving piano interludes full of tension, and then unexpectedlty it turns into something entirely else, when that last rhythm starts. Very bombastic and impressive, with striking vocal melodies.
