John Cage's comprehensive piano cycle Music for Piano 1-85 from 1952-1962 is a turning point in the sense of a radicalization of musical technique and a fundamental renewal of the conception of the composer's function and thus became a key work of 20th century music. Cage defines composing not as the codification of musical ideas, but as a process of writing. The fact that notation is the result of chance operations contradicts the traditional European concept of art. Cage thus arrives at a new understanding of conceptual and tonal originality, the potential of which is inexhaustible.

Experience Liebner's interpretation of Cage's piano works in Cy Twombly's Rosensaal.

The concert accompanies the exhibition "Five Friends. John Cage, Merce Cunningham, Jasper Johns, Robert Rauschenberg, Cy Twombly".
