Every week I write previews of the following week's radio for The Guardian Guide.I was complaining to a radio professional this week that it tended to be overwhelmingly Radio Four. "It's not surprising," he said. "They're the only people who make anything." And this is a guy who worked in the commercial sector.
I know there are cases of people doing preview-worthy programming beyond Radios 3 and 4 but they don't tend to be organised enough to send out preview recordings. I know some radio professionals look at this blog. If you're one of them, or if you know one of them, get in touch.
