I would like to suggest visiting Poland (and maybe different Central European countries as well) during the next EU trip in 2017.
A few years ago Loreena gave a great concert in Warsaw, why not to repeate this experience?
Maybe I'm not fully objective being born in Krakow, but I dare to say that the city with it's medieval heritage creates a perfect atmosphere for this kind of music, and maybe you should think about one of these venues planning tour in the EU:
1) Tauron Arena: http://www.tauronarenakrakow.pl/en/
2) Krakow Congress Centre: http://www.icekrakow.com/
It would be great having you here!
