en Altadefinizione. Writing with images: this is the departure point in this documentary. A portrait of four graffiti writers from Madrid and Barcelona: SUSO33, ISRA, SIXE and KAPI. They are part of a pioneering and illustrated generation in Street Art. For that same reason, their words and the development of four pieces (one by each artist) are the guides through this documentary. Shot in High Definition AEROSOL shows these four people's passion about a new, radical, urban and deserving of greater respect art.
