This apparently happened last month, but I just found out today. Epic symphonic power metal band Nightwish has parted ways with Annette Olzon who joined the band in 2007 to replace Tarja Turunen. Olzon was a somewhat controversial choice as she did not have the operatic vocals of Turunen. Tuomas Holopainen's compositions didn't change, but the delivery couldn't help but be different with Olzon who had a "smaller," poppier voice. Personally I ended up liking her more than I expected to, but I still missed Turunen's voice as did many other fans of the band.
The replacement singer for the time being is Floor Jansen. She was the lead singer for After Forever before they broke up. At this time she is just filling in for the remaining Nightwish concerts on their current tour. Whether she will continue with the band when they go back to the studio is up in the air. I'm excited about the possibilities. I always liked her in After Forever and her voice is definitely more operatic than Olzon's. Here are a couple of tracks from After Forever.
She definitely has the chops. I hope she does stick with the band.
