Rave on: global adventures in electronic dance music

Electronic dance music was once the utopian frontier of pop culture: now, three decades after the acid house 'summer of love', it has gone from subculture to the global mainstream.

But there are still hardcore believers upholding its DIY ethos - the techno idealists of Berlin and Detroit and the queer subcults of New York, the post-apartheid party people of South Africa and the outlaw techno travellers of France.

In 'Rave On', Matthew Collin travels the world to experience these unique scenes first-hand, talk to the key players and hear the story of how dance culture went global.
