From 1965 to 1970, he lived in Paris and became close to Lettrist Group (lettrism) (Isidore Isou, Maurice Lemaître), but also with French film underground milieu (Piero Heliczer, Michel Auder, Raphaël Bassan,Slobodan Pajic, Pierre Clémenti). For that period, he changed his name and became Antoine Perich, because Anton was not familiar a name in France. He was among the first activists to present, every week, programs of avant-garde and underground films in the American Center in Paris.
He moved to New York in 1970, became friends with Andy Warhol and contributed as a photographer to Warhol’s Interview. He also worked as a busboy at the legendary Max's Kansas City, where he photographed the scene as an ongoing art performance every night, along with exhibiting the photos on the walls.
In 1977-78, he designed and built an electric painting machine, an early predecessor of the inkjet printer. The development of this machine made Anton a pioneer of electric-digital-computer art.
In 1978, he founded NIGHT
as an interactive "gallery space" for his photography and the nightly activities at places such as Studio 54
. In 2006, he had a video retrospective at the Anthology Film Archives
, in New York.
