Bernd “Burnt” Friedman is one of the most relentlessly questing of experimental musicians. In over 30 years of making music and 25 years of releasing it, he has specialised in researching ancient, hypermodern and as-yet-undiscovered methods of soundmaking, including traditional and home-built instruments and the application of high-tech methodologies to established forms from around the world, in particular jazz, western club sounds, and African and Japanese styles.

It took the last 16 years of Nelson Mandela’s life, almost to the day, to bring his autobiography to the screen. South African producer Anant Singh eventually handed Mandela: Long Walk to Freedom to British director Justin Chadwick and screenwriter William Nicholson to make a film for international audiences. The iconic weight of a violent rebel who became a living saint can’t wholly be thrown off in this authorised (though freely made) biopic. It does, though, remind you that Nelson Mandela was very far from Mother Teresa.

Nelson Mandela had a nose for the dramatic gesture. The evidence is there in his speech at the Rivonia Trial in 1964, in his symbolic walk to freedom as he emerged on foot from captivity in 1990, his astute performance at the Rugby World Cup in 1995 and then finally in death, announced just as an epic new film of his life was being premiered in London, the seat of the old colonial power.

In 1997 I was in South Africa working on Truth and Lies, my book about the Truth and Reconciliation Commission, when the New York Times Magazine said that they were doing a major feature on Mandela. He’d been in office for three years. The photographs were taken in the presidential house, the former seat of the oppressors. It felt very surreal for me because even the décor was Cape Dutch furniture. It was not what you might imagine for a black president.

This near-legendary short play, devised by Athol Fugard with the actors John Kani and Winston Ntshona (who gave their names to its characters), was first shown in Cape Town in 1973, during the apartheid era. Its effect then must have been electric, and some of that visceral intensity still shone out in one of the pair's last performances of the piece at the Old Vic in 2002.

A single movement is all it takes. A wounded man is held at gunpoint, and instead of cringing away from the inevitable bullet, he lifts his head and looks his would-be executioner in eye. This simple gesture does not just save his life – it sets in motion a drama that will ultimately consume the lives of everyone caught up in it.

National Wake: A Walk in Africa 1979–81

Few real-life subjects of a film would allow themselves to be seen in the way Ginger Baker is in Beware of Mr. Baker. He’s violent, bullying, self obsessed, a control freak, irresponsible, sexist, foul-mouthed and harbours decades-long grudges. Since he doesn't appear to be ill, it's difficult to ascribe his behaviour to forces beyond his control. He does, though, love animals and is a legendary drummer. So that’s all right then. Not only is Beware of Mr.

Snow flurries outside, steam heat within. Writer-director Yael Farber’s transposition of Strindberg from a 19th-century Swedish estate to a contemporary farm in South Africa’s Karoo region on the eve of a storm is so painstakingly evocative that all worries about the latest publicity image – shades of blaxploitation, more Mandingo than Miss Julie – instantly evaporate.

Thanks first to a David Holmes cover version then to some recent reissues of his records, I knew the approximate story of Detroit singer-songwriter Sixto Rodriguez. Roughly speaking: intelligent but borderline down-and-out Detroit musician is discovered, makes two amazing albums in the early 1970s, fails to sell anything, and turns his back on the industry to find steady work and raise a family.
