From official site:
Finntroll's Future
What can I say folks, shit happens!!! And this shit seems far larger than any shit I've seen ever before. Not only did we lose a great vocalist, but I also lost one of my best friends in the band. I really don't know what to say. We founded this band together with Katla, and it feels so fucking bad to see him leaving us, but he really didn't have any choice. I refuse to accept that he's gone for good, and I'm looking forward for a day when he'll join us once again! We'll still do the fest's in this summer with an session vocalist, so none of the gigs are cancelled. We had some plans that I will take care of the vocals until Katla is able to return. Just remember one thing; We won't stop, no matter what!!!
