In 1948, the novelist and poet Jack Kerouac coined the name ‘Beat Generation’ for an underground, anti-conformist youth movement in New York. In the decade that followed, works such as Kerouac’s On the Road, Allen Ginsberg’s Howl and William S. Burroughs’s Naked Lunch (the last two sparkling obscenity trials that ultimately revolutionised American publishing) formed a distinct ‘Beat’ literature. Iain Sinclair has been described by the Daily Telegraph as ‘one of our most dazzling stylists’, and American Smoke, published this month, completes the trilogy he began with Hackney: That Rose-Red Empire and continued with Ghost Milk. In a talk introduced by novelist and screenwriter Deborah Moggach, he conducts a memory interrogation, touching on the past meetings, lost archives, chance discoveries, volcano obsessions and fated decisions of the Beats.
