Celebrated as a leader of London’s ‘Underground’ in the 1960–70s, and a leading British poet and performance artist of his time, Jeff Nuttall found fame through his critique of post-nuclear culture, Bomb Culture, which provided an influential rationale for artistic practice through absurdism but lost that recognition a decade or so later. Less well recognised, and with greater influence, is the distinctively visceral sensibility underlying much of his creative work, notably his poetry that draws on Dylan Thomas and the Beat Movement, his graphic drawing and luscious painting styles, and his pioneering performance art. This article argues that it is through these artistic expressions of visceral intelligence that Jeff Nuttall’s art and its long-term influence can now best be understood. It is intended to complement the Jeff Nuttall Papers in the Special Collections of The John Rylands Research Institute and Library, University of Manchester, deposited by the gallerist and poetry publisher Robert Bank (1941–2015), to whose memory this article is dedicated. Further papers have been added by Nuttall’s friends and relatives.
