For The Calvert Journal, Jonathan Bousfield revisits the “neo-abstraction, early premonitions of op-art, and the beginnings of computer art” seen in New Tendencies, an art movement in former Yugoslavia and one of “Europe’s forgotten avant-gardes.” Between 1961–73, five landmark exhibitions (feat. Julije Knifer, Vladimir Bonačić, Francois Morellet, Victor Vasarely, and many others) brought hundreds of artists, critics, and intellectuals to the city of Zagreb and “anticipated everything from video art to bio-art and robotics.”
