This documentary kicks things off with an insight into the history of the music genre, telling the story of how the giant bands of the 1970s changed rock for ever. With contributions from Alice Cooper, Josh Homme and Andrew WK, the programme journeys thought the greatest tales of extravagance, excess and indulgence from the world of rock and asks how the genre will continue to evolve in the digital age.
