I hear alot of talk about style but for me it comes down to everything you do, not just graffiti. Everyone has their own style. Who in you mind has style. There is not really a stand out. Alot has influenced my style, not only writer.
Music definitely has and so has life's general problems.
I really get into bands suck as Rage Against the Machine, Limp Bizkit, Korn, Deftones etc. As for life experiences, just stuff that happens to me will influence what I put up on the wall. I'll put that into the mood of the piece, the letter shapes and and the saying at the bottom, it all relates to how I am feeling and what I am going through. Painting is my only creative out put in the hip hop scene, unfortunately. As for Mcing the skills are just not there.
