A city like Rotterdam is the perfect playground for freerunners like Bart. When you do what you love, you tend to forget about your surroundings, so we designed a very diffuse auditory image of the city to match this feeling. We wanted to highlight the concrete jungle we are in, without laying too much emphasis on the little sonic details.

The overall flow of the sound design is very smooth and organic, until we are seeing Bart working in the gym to get back in shape. It feels almost mechanic and we’re following that with sound design.
