This collection of critical essays explores new approaches to the study of avant-garde literature and art, film and architecture. It offers a theoretical framework that avoids narrowly defined notions of the avant-garde. It takes into account the diversity of artistic aims and directions of the various avant-garde movements and encourages a wide and open exploration of the multifaceted and often contradictory nature of the great variety of avant-gardist innovations. Individual essays concentrate on cubist collage and dadaist photomontage, on abstract painting by members of the Dutch group De Stijl, on verbal chemistry and dadaist poetry and on body art from futurism to surrealism. In addition, the collection wishes to open up the discussion of the avant-garde to a thorough investigation of neo-avant-garde activities in the 1950s and 1960s. For decades the appreciation of neo-avant-garde art and literature, film and architecture suffered from a general and all-inclusive rebuke. This volume is designed to contribute to a breakthrough towards a more competent and more precise investigation of this research field. Contributions include a discussion of Warhol's multiples as well as Duchamp's editioned readymades, forms of concrete and digital poetry as well as the architectural "Non-Plan".The main body of the volume is based on presentations and discussions of a three-day research seminar held at the University of Edinburgh in September 2002. The research group formed around the Avant-Garde Project at Edinburgh will continue with its efforts to elaborate a new theory of the avant-garde in the coming years.
