Nightwish and Anette Olzon have decided to part company. The band is in the middle of a North American tour with Kamelot and faces yet another line-up change.

Full statement from the band and Anette Olzon: "Another chapter of the Nightwish story has ended today. Nightwish and Anette Olzon have decided to part company, in mutual understanding, for the good of all parties involved.

In recent times it has become increasingly obvious that the direction and the needs of the band were in conflict, and this has led to a division from which we cannot recover.

Nightwish has no intention of cancelling any upcoming shows, and as a result we have decided to bring in a substitute vocalist starting in Seattle 1.10.2012. Her name is Floor Jansen from The Netherlands (ex-After Forever, ReVamp), and she has graciously stepped in to help us complete the Imaginaerum world tour.

We are all strongly committed to this journey, this vehicle of spirit, and we are sure that this will lead to a brighter future for everyone. We forever remain excited about the adventures to come, and we are extremely proud of the two beautiful albums and the wonderful shows we shared together."

Elize Ryd (Amaranthe) and Alissa White-Gluz (The Agonist) stepped in for Anette this past Friday night (September 28th) at the Ogden Theatre, Denver, because Olzon was forced to spend the night at a local hospital. The singer later stated on her blog: "I was never asked if it was ok they used Elise and Alica in the show last night. I don't think it's a good decision they made and I'm sorry for those of you who came to see the whole band but got something else. But I was very ill and this decision wasn't mine."
