Fan-filmed video footage of NIGHTWISH's October 3 performance at The Warfield in San Francisco, California can be seen below.

Dutch singer Floor Jansen (REVAMP, ex-AFTER FOREVER) made her live debut as the frontwoman of NIGHTWISH on October 1 at Showbox Sodo in Seattle, Washington.

Jansen is handling lead-vocal duties on NIGHTWISH's current North American tour after the group parted ways with Anette Olzon at the end of September.

In a blog post on her official web site at FloorJansen.com, Floor said, "It is now 10 years ago I joined NIGHTWISH on tour with AFTER FOREVER as their support act. We stayed in touch ever since and that made the whole situation so much easier and smooth."

NIGHTWISH stated about the sudden singer switch, "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."

They added, "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."

Olzon joined NIGHTWISH in 2007 as the replacement for Tarja Turunen after the latter was fired in 2005.
