Here is their full statement:
“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.”
