Having completed his apprenticeship under Umberto Mastroianni, Icaro moved firstly to Rome and then to New York in the 1970s, where he embarked on his own research in the field of post-minimalism. After returning temporarily to Italy at the end of the decade, he participated in exhibitions on procedural and conceptual art, almost always in the form of actions: the early days of Arte Povera in Genoa, Teatro delle mostre at the Galleria della Tartaruga in Rome (1968), Arte Povera + Azioni povere in Amalfi, Live in Your Head: When Attitudes Become Form in Berne and Op Losse Schroeven in Amsterdam (1969). His work has always stood out from minimalist reductionism and procedural aesthetics because of its anthropometric and psychophysical dimension. In the 1980s Icaro settled permanently in Italy. His most recent solo shows include those at the Centro Arti Visive in Pesaro (2009), the P420 in Bologna (2012) and Peep-Hole in Milan (2014).
