Howl: The Poem That Revolutionised US Writing

Allen Ginsberg first read his poem Howl, at an art gallery in San Francisco in October 1955. It marked a turning point in American literature and is credited with starting the "Beat Generation" of American writers. Michael McClure, a fellow poet, took part in the reading that night. The programme was first broadcast in 2012.
