This is what I said on another board, after seeing Nightwish in Orlando:
"I've seen Nightwish with both Tarja and Anette. Anette has been heavily criticized, but I felt she did a good job, and had a good stage persona... but her voice has a certain little-girl sing-songyness to it which I am not a huge fan of. Tarja is a stronger vocalist in a technical sense, but to me, she has a certain "coldness" in both her voice and her stage persona. I just saw Nightwish with Floor yesterday... she brought a great combination of both personality and vocal skill to the table. As far as I've heard, Floor is not officially a permanent member... for now she's just there for the tour, but IMO it would be a good thing if she joined as a permanent member."
I arrived pretty early, and had a chance to talk to several people standing around in the long-ass line outside the venue... Nightwish's fan base has a lot of people who came to the band from angles other than the prog and power metal direction that most on this board came from, so most everyone I talked to wasn't familiar with Floor, and was saying "Who the fuck is this new singer!?". But everyone I talked to after the show, including a couple skeptics I had talked to earlier, was like "Holy fucking shit!".
