In the summer of 1956 Asger Jorn invited Constant to Alba, Piedmont, Italy, for a congress dedicated to 'Industry and the Fine Arts' initiated by 'Mouvement pour un Bauhaus Imaginiste' (International Movement for an Imaginist Bauhaus). At this congress Constant presented his lecture "Demain la poésie logera la vie" in which he pleaded for a free architecture which could stimulate a creative lifestyle rather than impede it.In 1952 Debord had founded the Lettrist International for which he was a writer, filmmaker and strategic activist. The 'Lettrist International' were also at the Alba congress and they pleaded for a unitary urbanism (the synthesis of art and technology). Later that year Constant visited Debord in Alba, which proved to be an inspiration for both.
