Here are my 2 concepts thus far. The first is based upon the workings of the human ear and basically trying to say that you should stimulate them by coming to this concert.
The 2nd is kind of the same idea but with emphasis on the brain. To be more specific the Temporal Lobe, which is responsible for hearing among many other things. The idea with this concept is to highlight this area of the brain in the images. Ideally this is what your brain would look like at this concert.
