Fan-filmed video footage of NIGHTWISH's July 20 performance at the Sotkamon Syke festivalat Sokos Hotel Vuokatin in Vuokatti, Finland, can be seen below.NIGHTWISH keyboardist and main songwriter Tuomas Holopainen has known the band's current touring vocalist, Dutch singer Floor Jansen, for more than 10 years already, having previously toured with her former band, AFTER FOREVER. Jansen made her live debut as the frontwoman of NIGHTWISH on October 1, 2012 at Showbox Sodo in Seattle, Washington following the abrupt departure of the band's lead singer of the past five years, Anette Olzon. Asked about the reasons for Olzon's sudden exit from the group, Tuomas told U.K.'s Metal Hammer magazine: "I'm sure it came as a shock to everybody. We came out with a statement [regarding the split], which pretty much says it all. It still is a private matter, and that's all we wanna say about it, like, ever. It was an amicable divorce, so to say, and made in good spirit, and we are just looking to the future. There really is no reason to go back into all the details and all that. I mean, this is not politics, this is a rock band." Regarding whether there is a chance that Floor will become the official new NIGHTWISH lead singer, Tuomas said: "The way that we have decided is that we're gonna continue with her until the end of the festival season in 2013 — just have fun, just do the shows the best we can. I mean, the atmosphere in the band is so good at the moment, [we want to] just enjoy this what we have right now. They try not to think about NIGHTWISH at all for a few months. Everybody take a little vacation. And we already have the rehearsal place for the next album booked in 2014 — from July to September. So that's how far we have planned. But when we do the last festival show next August, after that, it's gonna be total nothing for a few months. So I would say everything is possible, but that's really not the thing that we want to be thinking about right now, because there's absolutely no reason to."
