This is an awesome book called Parallel Strokes by Ian Lynam about the relationship between typography and graffiti. Here's the summary for it:

Parallel Strokes is a collection of interviews with twenty-plus contemporary typeface designers, graffiti writers, and lettering artists around the world.

Interviews within include conversations with pan-European type design collecitve Underware, Japanese type designer Akira Kobayashi, American graffiti writer and fine artist Barry McGee/Twist, German graffiti writers Daim and Seak, American lettering artist, graphic designer and design eductor Ed Fella, among others.
