There's a gap here - not only for a production company to stage independent events of the Colab / Coke Fest / Ampli5 calibre in the coastal region, but also for a regional radio station that can fill the space being sorely neglected by the nationals.
I seem to recall there being some developments at ICASA involving greater availability of FM licenses, which may mean that an east-coast based station which targets the same demographic (14-35, independently-minded, up to date with global trends) could make name and that all-important crown. This in an area that, let's face it, has got a truly shocking shlock jock station situation in an unmentionable broadcaster who flies a red and yellow flag. A further situation exists in the majority of national and regional stations being shy of playing new local material, regardless of support bases on the ground. Mass media is tailored to suppress all but that which comes through the right channels, for which you can read 'is owned by the same holding company' or 'has enough money to pay its way onto the playlist'. Which is all yesterday's news. Boring.
Between Richards Bay and Port Edward there exists a substantial audience which prefers not to hear Celine Dion, Michael Buble or Bryan Adams. Ever. Yet nobody plays what they want to hear. Mind the gap? Somebody's gonna.
