A monograph on the Brussels-based duo Hell'O presenting a retrospective of their artistic productions, exhibitions and artists' books as well as their large format interventions in the public space ("murals"). More than 225 visuals retrace the path of these young artists whose universe both strange and familiar and their ever recognizable but constantly renewed style have conquered Europe and the United States. From their first black and white drawings to more abstract paintings in color. The course will immerse the visitor in total immersion also in the heart of collective works created in situ specifically for the exhibition. Many private collectors, galleries and public institutions from Belgium and abroad have agreed to lend us their works for this first "inventory" of their work. Exhibition: Musée des Beaux-Arts, Mons, Belgium (28.04.-29.07.2018).
