It was the greatest invention in the history of pop music - the rock god who came from the stars - which struck a young David Bowie like a lightning bolt from the heavens. When Ziggy the glam alien messiah fell to Earth, he transformed Bowie from a prodigy to a superstar who changed the face of music forever. But who was Ziggy Stardust? And where did he really come from?In a work of supreme pop archaeology, Simon Goddard unearths every influence that brought Ziggy to life - from HG Wells to Holst, Kabuki to Kubrick, and Elvis to Iggy. Ziggyology documents the epic drama of the Starman's short but eventful time on Planet Earth... and why Bowie eventually had to kill him.
