In Wald, three voices are confronted with one another. The actors Tom de Hoog and Hilde Wils tell us the stories of those who were interned in the concentration camps and of those who try to imagine what it was like (texts by Heinrich Heine, W.G. Sebald, Marguerite Duras). The third voice is that of music. Seated at the piano is Alain Franco, who presents us with a musical discourse, with music from Zimmermann, Brahms, van Beethoven, Robert Schumann a.o.
