I created this work while contemplating my perception and attitude towards the city of Sofia, where I had been living for more than a year and a half by that time. I walked the streets, recording various sounds: trams, the subway, passing cars, as well as the atmosphere of parks, busy and quiet streets. In the end, I assembled a mosaic from this. The video sequence turned out to be quite simple, but it conveys the feeling of hidden energy and electricity present in the city.
