Enigmatic Street Art by Escif

I know I have been a lot into street art and graffiti lately but suddenly I started to think about what are and should be their proposals. As art on a general meaning, this other media should serve as a support to express ideas and feelings, not just shapes and colors. I've been watching the work of this Spanish artist called Escif and I noticed that he got into a really conceptual and minimalistic aesthetic but still quite impressing and shocking sometimes. He's a great proof that a great concept can enhance any artwork.
