fatcap and why streetart

Here's a quote I found on http://www.fatcap.com/ about why people make street art and why art in general is important. I found this to be a concise explantion of why artsts do what they do, with examples!

here's the specific link: http://www.fatcap.com/article/the-veil-and-street-art.html

 And so we have the campaign against big brands led by the street artist Zevs, which mobilized public opinion and the media, and the works of Bansky that are appealing because they generally transmit an intelligible, funny or sometimes disturbing idea. Remember, for example, when he painted the wall separating the Palestinian and Israeli people. Another well-known example: the celebrated posters of Shepard Fairey (aka Obey) who subverted the imagery of political propaganda...sometimes to political ends.

The main goal of art is usually to create something beautiful and not necessarily to convey some sort of message. However, certain works of art do happen to be provocative and in the absence of communicating a clear and intelligible message, they shock, pose questions, or force us to confront our preconceived notions.
