I love viking/folk metal too! Folk rock is great as well (think Omnia, Faun, Irfan, Moon and the Nightspirit, and lots of others, but I think those are more 'metal' than 'rock', hmmm...)
Well, as for escapism, I LARP, which is probably pretty escapist stuff, lol! I always larped as a female char though, until I found out that playing as the 'opposite' gender is actually accepted (not only among transpeople), as long as you can pull it off (Heck I can!

). So since shortly I'm happily playing a male character. Even though it's not real, and OOC

Out Of Character) people still talk to me like a girl (though some kept calling me 'him' just for fun and to tease me, and I actually like it, lol! I told them they should call me Erik when calling me a guy OOC, and not my IC

In Character) name, telling them it's my 'male name', and they happily bought it, thinking it was some fun joke. So now I got the "nickname" Erik amongst my LARP friends, lolol! If they knew...!

) Even though they see it as a joke, I damn love it!

And before... I used to play lots of games (mostly Runescape, WoW for a few months, but also some 'non internet' games) and write stories as well. When I was a kid I used to draw A LOT (still do, but less, actually), and play 'adventure' with my action figures (I actually identified with none of them, as they were just characters of their own, but funnily enough they were all guys, lol), but whether that counts as escapism... I dunno, lol! Would building with blocks count as escapism too then?

And lastly lots of music. Listening, but also singing (I'm not that good, really. I recorded myself and even though I hit the notes I sound pretty nasal and just crappy), and playing piano (improvising, mostly, but also learning a new song now and then, or practicing a new technique)
I think mainly Pink Floyd, and viking/folk/celtic metal are good for 'escaping' and getting some ->-bleeped-<- out. Though hard rock can be great too.
