For the second time in the history of Organised Sound, a call for submissions led to a response that was voluminous in number and substantial in terms of breadth and quality. As Barry Truax mentions in the editorial above, it was decided that we indeed had received sufficient material to cover two issues. Given the fact that calls for submissions for the two subsequent issues had already been sent out and, by the time of writing this addendum, received, it was decided to publish its follow-up edition in a year’s time. Ironically, the first time this occurred it was on a somewhat related topic. In this case, Katharine Norman had proposed a call regarding ‘Sound, Listening and Place’ for issue 16(3) (December 2011). Its part two was also published a year later.

I have known our guest editor and ‘OS’ long-standing regional editor, Barry Truax, for many years and have always respected his work as an artist, thinker and developer. One trait that readers may not know about him is his rigour in anything he undertakes, whether it is teaching, scholarly research or acting as a guest editor to this issue. Neither he nor I expected so many submissions. He not only coordinated the reviewing process but also actually looked at all these texts closely and, in fact, copy edited most, in some cases more than once. This has been a huge task and I want to share my gratitude not only for the enormous amount of work involved, but also for his encouragement to many authors and the quality of his responses as a reviewer. Clearly this subject has resonance at the moment. He has played an important role in ensuring that these interests have evolved into what is being presented in these two issues.
