If a tree falls in a forest and no one is around to hear it, does it make a sound? No it doesn’t. On this episode of Sound It Out we think about the relationship between art, artifacts and their audiences. Do audiences have to get together in person or can they exist in disparate locations across the globe? Do members of audiences need to know each other in other contexts? What norms govern the behaviour of an audience? McGill’s Prof. William Straw of the Department of Art History and Communications Studies discusses these matters, and I read selections from Jean-Paul Sartre’s Critique of Dialectical Reason which examines the indirect gatherings involved in a radio broadcast. This episode originally aired on CFRU 93.3FM on July 30th, 2015.
