Book excerpt: Dan Graham's Rock My Religion (1982-84) is a video essay populated by punk and rock performers (Patti Smith, Jim Morrison, Black Flag and Glenn Branca) and historical figures (including Ann Lee, founder of the Shakers). This coming together of several narrative voice-overs, of singing and shouting voices, of jarring sounds and text overlaid onto shaky, gritty images, proposes a historical genealogy of rock music and an ambitious thesis on the origins of America. In this illustrated book, Kodwo Eshun examines this landmark work of contemporary moving image in relation to Graham's wider body of work and to the broader culture of the time, especially in relation to history, popular culture, and individual and communal identity.
