| These cities are inevitably a reservoir of energy and violence, of vitality and depression, and recent generations of artists, conditioned by all this,
 have produced an art of documentation that records the negative side of the
 modern city. The city with its unstable equilibrium is in continual tension
 between the speed at which communication flows and the reality of a place in
 which specific and limited identities coexist and assert themselves.
  Necessarily, at this moment in time in which terrorists have put on a sort of media performance that has visually upstaged art, a different "creative
 trend" is emerging that is capable of representing new contents and open
 to small-scale utopias and unprecedented values of construction.
  The model for all this is Laurana’s “Ideal City,” which representsthe faith of Renaissance man in art, reason and planning. In the last century
 it was undoubtedly Le Corbusier’s “Radiant City” with its "Modulor"
 (in which growth is regulated by a Fibonacci series of numbers) that constituted
 a model and a planning parameter, and one which is still relevant.
  The same spirit can be found at other times as well, for instance in Futurismand in the more farsighted research of the historic avant-garde movements: Umberto
 Boccioni, Antonio Sant’Elia, Tatlin, Malevich, Kurt Schwitters, El Lissitzky,
 Louise Nevelson, Gaudí and Mondrian. We can, in this way, identify a
 line taken by an art that has become habitable, in relation with other expressive
 languages such as architecture, design, music, drama, and photography.
  The “Radiant City,” which investigates the constructive aspectof the visual representation of the metropolis, runs all the way from the Renaissance
 model through the historic avant-garde and the neo-avant-garde to the work of
 the most recent generation of the new millennium. Among those who experimented
 with it over the period from the fifties to the seventies were: Lucio Fontana,
 Robert Smithson, Mimmo Rotella, Denis Oppenheim, John Cage, Joseph Beuys, Daniel
 Buren, Hans Haacke, Lawrence Weiner, Panamarenko, Dan Graham, Kingelez, Nam
 June Paik, Superstudio, Bernd & Hilla Becher and Luigi Ghirri.
  In particular, Gordon Matta-Clark (1943-75) deconstructed, punctured,and reassembled fragments of architecture through real interventions and photography,
 utilized as a field of virtual action in which to reshape the condition of a
 separate city into a livable whole.
 Vito Acconci has moved on from the somatic zone of the individual body to analyzethe vaster area of the body social through concrete interventions that modify
 the appearance of the city. His work is placed at the service of a public that
 utilizes and contemplates the art form integrated into the landscape. The desires
 and needs of daily life have been reformulated by some young artists, especially
 in Europe, into a sort of "behavioral architecture and design" that
 goes beyond the traditional relationship between form and function of the city
 and the object, as in the case of the Roman group Stalker and the Dutch one
 Droog Design. With his igloos Mario Merz anticipated the convergence between
 art and architecture through forms that re-establish the balance between human
 beings and their environment.
  The artists most representative of more recent research are: Thomas Struth,Cristina Iglesias, Julian Opie, Günther Förg, Thomas Hirschorn, Costa
 Vece, Tobias Rehberger, Armin Linke, Frank Thiel, Pierre Huyghe, Kendell Geers,
 Grazia Toderi, Adam Berg, Amador, Jordi Colomer, Olivo Barbieri, Rafael Lozano-Hemmer,
 Luca Vitone, Carlos Garaicoa, Nils Norman, Italo Zuffi, Doug Aitken, Emily Allchurch
 and CRIMSON.
  If the metropolis has turned into a megalopolis, the computerized systemof social communication via the internet has found a means suited to its context.
 A territorial identity in transition has gained the upper hand, in the name
 of an ethnic pluralism that is nevertheless homogenized by a hypertechnology
 which invades every field, completely altering the relationship of the human
 being with reality, under the banner of chemistry and fragmentation. The drugs
 of the future will follow the evolution of what are the pillars of our society:
 liberalism, individualism, productivity at all costs. The great multinational
 pharmaceutical companies are on a war footing. We are entering the era of psychochemistry,
 whose substitutional products have just been an already obsolete precursor and
 Viagra a symbolic example sent out to test the waters’ (Claude Olievenstein,
 Droga. Un grande psichiatra racconta trent;anni con i tossicodipendenti, Cortina,
 Milan 2002).
  Such an outlook impinges on the creativity of the most recent generationthat of Web Art, which lies in the “concept stores,” dominated by
 the figure of the “veejay” which his “scratch” eye mixer
 of images even on the laptop, where they are assembled into B-movies, news footage,
 trash TV, pursuing the aesthetics of the sample not covered by copyright. The
 chemistry of montage still dominates the new imagery of the century, liquid
 and dematerialized, modified and artificial, i.e. outside any parameter of the
 plausible. In a post-Darwinist and post-ideological age, art is a forum, to
 paraphrase the Romantic Victor Hugo: the desire for a visibility over the horizon.
 In this macroscopic urban perspective, the city condenses within itself a new
 multiethnic population on built territories and geographic areas.
  One undoubted emblem of an architectural globalization is the systematicdesign of the bridge, as an object and link between different places, separated
 by distance and often by social diversity as well. Foster and Calatrava are
 the creators of architectural forms that marry function and fusion: new forms
 of the bridge. This urban fervor seems to be contradicted by the autarchic and
 iconoclastic shelling of the two giant Buddhas of Bamiyan, in Afghanistan, by
 the Taliban: a tribal extremism in defense of an all-too-modern Islamic identity
 against the homogenizing threat of Western globalization…
