Vilém Flusser has been most influential with his seminal work on the techno-imaginary. However, several of his essays on composition, sound and listening show the significance that music had for his thinking. Thanks to Annie Goh, one of the editors of Flusser Studies 17, two of Flusser's important early manuscripts on music and sound have recently been translated and published. Flusser wrote these lectures, entitled On Music and On Modern Music, in 1965, at a time when the very concept of western music had been seriously challenged by the post-WWII avant-gardes. Today, in the aftermath of the massive digitization, algorithmization and cybernetization of almost all aspects of western society, culture and politics, Flusser’s gesture of listening, as we argue in this article, might be more relevant than ever.
