OSP is a small team of designers from Brussels, Belgium. Their daily work includes different aspects of the publishing cycle, operating from the assumption that tools-of-the-trade, typography, design decisions, distribution and content licensing are somehow connected. Present for the interview were OSP members Femke and Harrisson Snelting.
The interview comes as two mp3 files (with an abrupt break between the two parts). You can access the interviews at http://ospublish.constantvzw.org/?p=221 where they will start streaming immediately.
The files are also mirrored here with permission of OSP and George Williams: first part of the interview; second part of the interview.
PS: Here is a link to an interview of Femke Snelting herself.
