A journey through the history of rock music, continuing with the story of stadium rock. For some artists, size really did matter. In the early 1970s, rock moved out of the festivals and clubs and into the stadiums. We Are The Champions shows how the power and volume of Led Zeppelin and the showmanship of Queen 's Freddie Mercury were both perfectly designed for the stadium and how it was only when playing to audiences of tens of thousands that their music came into its own.
