BLU is just another talented, infamous graffiti artist, but what I like about BLU is his incredible graffiti stop-motion videos he creates. After stumbling upon his youtube video 'MUTO,' I've been following this artist's work for almost two years. Not much is known about BLU, except he's from Argentina and travels the world creating massive murals on huge walls for everyone to see. The one above was done in Barcelona.
According to wikipedia (a very unreliable source) he's been active since 1999. He's done a few collaborations with other famous artists which are also up on Youtube. I've noticed his style evolve into more social and political work. Sort of like Banksy's stuff. A very short and sweet, sarcastic way of taking a stab at the world's problems
