This 45 min. video spurned the graffiti story in this issue of MRZ. The video focuses more on the taggers and artist  (yes, they are artist in the strongest sense) on the West coast, mostly L.A.

The artist (24 of 'em), try to explain what their art means to them. Some do it better through their art. I highly recommend this video to anyone who is interested in graffiti, art, politics or into understanding different cultures. You will never look at any graffiti the same way again.
