Ich ruf zu dir... is unfinished title of Bach´s cantata, which is the main musical motif of Tarkovsky´s movie Solaris (1972). The cantata served as a model for creation of five graphical scores – libretto to their music-dance interpretation. The intepretations of these graphic scores under the direction of Zuzana Žabková are performed by the impro musical dance company Otvorené dvere (Open Door).
