BBC4 in the UK has been running a three part documentary series called 'Music Moguls: Masters of Pop'. The first was about the role of managers, the second about producers and the third [[airing this Friday) about Public Relations/PR. I felt the second part about the role of producers was fabulous. It's presented by Nile Rodgers [[and appropriately, is very well produced!). Highly recommended viewing [[and includes a contribution from Lamont Dozier among others)! It's available on-demand for another 3-4 weeks, although I'm not sure if it's accessible from outside the UK.
