If you are interested in experimental electronic music and visual art i strongly recommend you to visit Norbergfestival in Norberg ,Sweden that is taking place between 27-29 july.
I have been visiting that festival from now and then and one of the stage area which is in a old industrial smelting building called “Mimerlaven” still mesmerizes me.
I still have not found a more awesome industrial building to have concert in than Mimerlaven.
At Norbergfestival focus is pretty much towards techno/minimal-techno but you will find a lot of other goodies there to.
The amount of people who visit the festival stands around 1200 so it is a small festival but you always meet interesting people who are into electronic visual art and music.
A sample of artists that will perform will be:
