Laura Jean Cameron (GPPL) and Matt Rogalsky (DAN School of Music; Film and Media) gave a presentation to the London Group of Historical Geographers last week entitled "Sound Microscopy: Bill Gunn's field recording and the ethics of slow". The topic is part of their (slow) collaborative research creation project on listening and early Canadian field recording practice. An audio recording can be found on the website of the Institute of Historical Research, School of Advanced Study, University of London.
