Ultima Festival
Most streets and squares of Oslo display a lot of digital signals. Magnetic waves are dense and all over the place.
There are some further special highlights which I did not hear before: The self driving busses named Mads and Oda in the harbour area sound similar to a science fiction sound track.
The escalators in the central station from track 1-11 have differently colored neon light arches, which are quite relaxing and beautiful to listen to when you go down to the train platforms.
