James Siena has been a must-see artist on the New York art scene since the 1980s. His works compose complex abstractions based on a series of self-imposed rules, basic units that he repeats obsessively and infinitely and which he calls "visual algorithms". They have earned him the recognition of the greatest institutions such as the San Francisco Museum of Modern Art (San Francisco), the Metropolitan Museum of Art (New York), the MoMA (New York), the Miami Art Museum (Florida) and the Whitney Museum of American Art (New York). Xippas' booth for the 2021 edition will offer a retrospective reading of his drawn work, from the late 1980s to the present day. The works selected among the other artists will be articulated around this focus with the objective of revealing the capacity of the line to create impressions of spaces, whether narrative or abstract.
