The eccentric, manic, often moving collaborative explorations of London's hidden streets, cemeteries, parks and canals by photographer Marc Atkins and writer Iain Sinclair were first recorded in Sinclair's highly acclaimed 1997 book Lights Out for the Territory, praised in the Guardian as "one of the most remarkable books ever written on London." Liquid City documents Atkins and Sinclair's further peregrinations, focusing on the city's eastern and south-eastern quadrants. An array of famous and lesser-known writers, booksellers and film-makers slip in and out of Sinclair's annotations, as do memories and remnants of the East End's criminal mobs. The title Liquid City is meant to evoke the Thames, which flows silently through the photographic and textual narrative, and to suggest the changes London has undergone and, like all cities, is constantly undergoing.
