In an interview, Cain Ferreras gave his opinion on Urban art: I think that both in Salamanca and elsewhere it contributes to humanizing the environment a little. After all, most of them are handcrafted and personal works. Altogether a diversity is created that reduces monotony to the cities.
Focusing on painting, I think that all this was already provided by graffiti; In my opinion, modern urban art has served to make it better viewed socially.
