Some years back, a friend of mine thought to himself: how about a concert at Akershus - a huge, 400 year old castle and fortress  in the center of oslo, by the sea. Last saturday it became reality.  2 years of planning and preparations by him and some other friends of his resulted in a big event with 17.000 spectators. I was there with my camera. Heres some shots from the headline concerts with Røyksopp and Jean Michel Jarre.
