"The American Tornado. Art in Power 1949-2008 presents essays devoted to the major artistic movements - from Pop Art, Minimal Art, Conceptual Art, Land Art, and Body Art all the way to the most recent manifestations of Graffiti Art and the New Artistic Media - and the key figures involved in them. The vast amount of material produced on American art, a selection of which is gathered together here, demonstrates the particular attention with which the Italian art historian documents present-day artistic events and keeps his critical views up to date." "Since the critical reading developed in these pages by Germano Celant is the fruit of first-hand knowledge and experience of the art in the places and periods in which it was and is produced, the book presents itself not only as an historical compendium of American art since the 1950s but also as an eye-witness report from someone who is still sincerely and wholeheartedly involved."--Jacket.
