Alcest will come to Finland as well, and I'd love to see them live (I missed a festival gig earlier this summer), but they're "just" supporting Katatonia. I don't really like (new) Katatonia that much, and I'm afraid Alcest will only play a really short set. Still, I'll probably go despite of that.
I'm also starting to consider going to Switzerland in December to see Eluveitie (& Friends), since they seem to be completely neglecting Finland this year -- I think they have played or will play in every single Nordic country apart from here in 2012.
It would be absolutely amazing, but I'd have to go alone, I have pretty much never traveled (I've been to a foreign country like 5 times, three of them to Sweden, which means a 2-day-trip, and never been in a plane in my life) and honestly, the idea of going that far just to see one band seems a bit weird.
