Drawing on a wealth of unpublished archival materials, Stephen Voyce offers new and insightful comparative analysis of poets such as John Cage, Charles Olson, Adrienne Rich, Kamau Brathwaite, and bpNichol. In contrast with prevailing critical tendencies that read mid-century poetry in terms of expressive modes of individualism, demonstrates that the most important literary innovations of the post-war period were the results of intensive collaboration and social action opposing the Cold War’s ideological enclosures.
