Nightwish has just announced its new bass player, who will replace Marco Hietala and will take part in the upcoming world tour in support of the "Human. :II: Nature." album. The band's new bassist is Jukka Koskinen (Wintersun). 

Tuomas Holopainen and co. said: "Finally we can share the awaited news with you all! Let's welcome Jukka Koskinen on board!"  and Koskinen added: "I couldn't be more honored to be part of the vehicle of spirit of Nightwish on its onward journey sharing special live moments to come on the 'Human. :II: Nature.' tour with all of you out there!".

Koskinen made his live debut with Nightwish at the first of the band's two interactive "An Evening with Nightwish In a Virtual World" concert experiences that have kicked off the "Human. :II: Nature." run. By the way, these two virtual concerts were a big success!

Marco Hietala announced his departure from Nightwish in January, explaining in a statement that he hadn't "been able to feel validated by this life for a quite a few years now". Tuomas Holopainen said that Hietala's decision to leave the band "came as a bit of a surprise."
