The influential director Krzysztof Warlikowski creates an enthralling diptych that has not existed in this form before. He merges the two one-act-operas of Hungary's greatest composer Béla Bartók and the brilliant French composer Francis Poulenc into one amazing work. A great achievement with pure emotions and passion in an excellent interpretation by the exceptional singer Barbara Hannigan in the title role of La Voix Humaine.
