The show is one of the three-part series Music Moguls, which is due to air in January 2016. The show will be narrated by a small group of influential insiders and their artists, who have helped shape the face and sound of popular music around the world.
Unlike the traditionally told tales of debauchery, excess and exaggeration recounted by artists, the series will focus on the untold history of the pop and rock world from the people who work behind the scenes.
Edwards said: "We all know what a significant role PR plays in British public life nowadays, but not many people realise that its roots go back five decades ago to the start of the music business as we know it now. In this film I lift the lid on the unseen, uncredited, often unappreciated and unsung PRs that helped create an industry that now employs something like 60,000 people."
Edwards narrates episode three, which delves into the publicity plots that have helped shape some of the world’s greatest artists. In the programme Edwards discusses how he and other PRs, such as Barbara Charone and Andy Saunders, cultivate new bands, manage crises and attempt to maintain the reputation of their longstanding clients.
Featured artists include Debbie Harry, Ozzy Osbourne, the Sex Pistols, Uriah Heep, Brett Anderson and Hugh Cornwell.
In September the former editor of The Sun, Dominic Mohan, joined Outside as CEO.
