FROM his Los Angeles workshop, Shepard Fairey is dealing with perhaps the gravest hazard any self-respecting guerilla artist can face: success.

Fairey, a fixture on the global street-art scene for a quarter of a century, is putting the final touches to his first solo London show in five years. He is also preparing the cover art for a re-release of Led Zeppelin's back catalogue and has just finished a collaboration with Neil Young.
