The creation of the "Etudes Australes" in 1974 marked the beginning of a collection of virtuoso etudes.
The highly complex piano composition is divided into four individual books with a total of 32 etudes. John Cage based it on maps of the southern night sky ("Atlas Australis"), from which planetary locations are selected by means of random operations and translated into notes.
These planets, translated into notes, were notated in two staves each - always covering the entire keyboard for both the right and left hand. The moment of chance thus becomes an aesthetic category in this work.

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".
