American experimental music innovators George Lewis and Roscoe Mitchell will perform with Lewis's interactive computer system Voyager, which was one of the earliest strides in the development of a real-time relationship between a music-making machine intelligence and human musicians. Both Lewis and Mitchell are long-term activists for the visibility of African-American composers and have left their indelible marks through visionary work with ‘non-musical’ noise and computers. On the same programme, Marcus Schmickler and Julian Rohrhuber will explore the Mind Reader, an invention that helped lay the foundation for machine learning in the midst of the Cold War.
