This book is number 10 of Avant Garde Critical Studies and is based on the Yale Symphosophia held in April 1995 which was originally conceived to honor the Brazilian Concrete poet Haroldo de Campos on his 75th birthday. The symposium brought together over forty poets and performers and produced this volume of review and critical appraisal of an international perspective of avant garde poetic production. The volume includes the scholarly papers delivered at Yale and is divided into the following themes: Experimentation and Its Historical Moment; Experimentation in the Language Arts; Concrete and Neo-Concrete Poetry including Memoirs of Concrete; The Yale Symphosymposium on Contemporary Poetics and Concretism - A World View from the 1990s. The Sackners were invited to attend the symposium and were noted in the preface as follows: The Symposophia benefited from the perspectives of Ruth and Marvin Sackner, professional collectors representing the most extensive and complete archive of Concrete poetry in existence. The book is illustrated with two color plates by Severo Sarduy and two by Augusto De Campos. Athough one section head reads 'Concrete and Neo-Concrete Poetry,' there is no specific details regarding 'Neo-Concrete' in the chapters collected under this heading. -- Source of annotation: Marvin or Ruth Sackner.
