Escif is Valencia's most famous street artist whose work often depicts spooky black and white bird-like people. There's an artistic style to his work that sets him apart from more traditional graffiti and even mural painting.
He has said:
"I see graffiti as a necessary symptom of life in contemporary cities. A painted wall represents a way of using the city that is not thought about socially (though it becomes more so every day). It seems very interesting to me that people that live in a city do not settle for using it according to imposed rules; they invent new ways of utilizing it."
