Journalist Bjorn Almqvist and photographer Emil Hagelin have been following WUFC and some of their friends for several years. The reader will encounter a new world through exhaustive interviews and direct reports. They followed the writers from making preparations in their homes to descending into dark tunnels to write. They risk injury and fines all year round to see their name on the trains. Their lifestyle can be hard to understand. Why do they write, how do they see their work, and what sort of people are they really? Most graffiti books concentrate on the pieces themselves. The authors wanted to show what the crew's lives look like, and how graffiti appears on Joe Blogg's wall or the subway train he takes to work every morning.
