As a student András Halász called together several avant-garde artists to take a stand against the enforced communism. They opposed the artistic limitations that the regime had thrust upon them. Halász displayed his work in private houses, community centres and alternative clubs. He experimented with different art forms such as photograms, conceptual work and performances. In 1978 he left Hungary and from then on worked frequently both in Paris and New York, thus escaping the restriction of artistic activities in his homeland. Since 1990, the artist has been able to visit his native country legally and since 2005 has been living once again in Budapest, where he teaches at the University of Fine Arts.
