After making The Battle of Orgreave, this big, expansive art work about the UK, I needed a change of scene. Luckily I was invited to the US for a three-month residency – I ended up staying for a year. While I was there I wrote a guidebook to the state, which included a treasure hunt and a CD, and I also bought a piece of land. The tour is based around people, Californians: two former Black Panthers in Oakland, a burlesque dancer from the 1950s, and a Cuban exile with a shady past, among others. This was more of a guide book to people than to places.
