This episode celebrates the club. From Studio 54, The Loft and Paradise Garage to Shoom, illegal raves, The Hacienda, Cream and on to the contemporary megaclub brands in Las Vegas and Ibiza.

In the final, part we tell the story of the DJ. With a cast that features todays biggest DJ stars alongside house pioneers, we plot the DJ path from invisibility to centre stage. How is it that people who play records are today's highest paid music stars?
