As any grime or UK garage fan will be aware, pirate radio in the UK was an unrivalled and exciting source of underground talent. The history of pirate radio stretches much further back into the 1960s and earlier when pirate radio was broadcast from ships in international waters.

A crucial period of pirate radio that is often overlooked was the 1980s when a new wave of pirate broadcasters emerged. The "seafaring swinging sixties" pirates of the '60s had been legitimised but there was still nowhere to discover black British music, despite its huge popularity. The new wave of pirates were now broadcasting from council estates and tower blocks in London. As a new BBC4 documentary shows, these broadcasters and stations were hounded (much like the grime and garage generation that followed) by DTI enforcers and the police.

Presented by Rodney P (whose own career was supported largely by pirate radio), the doc delves into that period with interviews and archive footage of DJs, station owners and even the enforcers themselves. Though the pirate radio in the '80s gave us early warehouse parties, KISS FM and a raft of household names who are now celebrated in the mainstream, these figures were considered outlaws in Thatcher's Britain.
