2/3 When hip-hop broke free of the confines of the ghetto, a battle began between moral crusaders and the musicians who claimed the right to talk about the world they inhabited. Narrated by Shaun Keaveny. (AD)

DOCUMENTARY
Blood on the Turntable 9.00pm BBC3
The series about tooth-and-nail feuds in the music industry continues with the impact of hip-hop on conservative USA.
The film centres on two frantic furores of the early 1990s: the obscenity trial that followed 2 Live Crew's album As Nasty as They Wanna Be and the censorship slapped on Ice-T for his track Cop Killer.
The artists' defence was freedom of expression, while their detractors lamented that, as Christian campaigner Jack Thompson says here, "the kids are swimming in raw cultural sewage".
It's an extraordinary story, but the heavy-handed narrative suggests it's a cut-and-dried issue and the rappers are beyond reproach. And many won't last the first ten minutes, which, paradoxically, are stuffed with expletives and gratuitous scenes of naked dancers. (Mark Braxton)
