Scandinavia and Northern Europe is where it's at right now with new concert halls.
Danish Radio Koncerthuset (Jean Nouvel)
Hamburg Elbe Philharmonie (Herzog & de Meuron)
Oslo Opera
Kristiansand, Norway, Kilden
and just for shameless self promotion, where I will be working when it opens in 2013, The Music House of the North in Aalborg, Denmark by Wolf D. Prix/Coop Himmel(b)lau
