Banksy is a UK-based graffiti artist, and arguably the most famous spray artist in the world.

He has been taking a residency on the streets of New York every day for the month of October, which has taken the city by storm.

The 12th installment is called Concrete Confessional.

Many of his pieces are accompanied by an Audio Guide, which further explains the art, often giving tongue-in-cheek commentary. He provides a 1-800 number to dial, which is next to the painting, and spectators can select an option to listen for an audiovisual experience.
