In 1986, Kurt and UC Davis graduate student Tamara Blanken produced a replica of Duchamp's A Bruit Secret (With Hidden Noise) and planned an event at the University of California at Davis during which it would be displayed and Kurt and Tamara would each give a presentation. Kurt generated a set of notes for his talk, which included some slide presentations. Accordingly, this document is adapted from his typewritten notes, and images added corresponding to the slides he displayed. Tamara's account of creating the replica is also available. A transcript and recording of Kurt's lecture is also available.
