This collection showcases the liveliness of British avant-garde fiction of the 1960s, which is diverse in its aesthetic practices and (sometimes) divided in its politics. It brings together a selection of original, research-led essays on more than a dozen avant-garde British writers of the 1960s, revealing this to be a crucial – and crucially overlooked – period of British literary history. Via detailed readings of authors such as Ann Quin, B.S. Johnson, Alexander Trocchi, Maureen Duffy, Alan Burns, Christine Brooke-Rose and many others, the contributors reveal the diversity of material produced in this period and trace the complex relations of influence and indebtedness between the 60s avant-garde, earlier modernisms and later postmodern writing. The volume shows that the 1960s is an even more vibrant period of literary experiment in Britain than might previously have been supposed – and that the avant-garde fiction produced then rewards our renewed attention to it.
