I just came across this animation of one of György Ligeti‘s few electronic compositions Artikulation (1958). This animated sequence puts my collaboration with Piotr Szyhalski, Post-prepared Piano, in historical context. The visuals for Ligeti’s piece were created by Rainer Wehinger in response to the music, while in Post-prepared Piano (see the animated sequence) the visuals are converted directly into an electronic version of an existing work through a computerized process.
