Got a bit annoyed at the posh voice telling me rave happened because of Thatcher. A variety of factors at work, surely? And the way the same old stories about house/detroit/kraftwerk etc get trotted out like simple cause and effect science, like storytelling/myth-repeating presented as science.
I did find interesting, though, the idea that techno's success in Europe led to the african-american rejection of the form as some white folks music.
