Originally aired on public television, this look back at the history of rock and roll radio tells the story of the brave deejays who fought to bring vital music to the masses, and the efforts of government and big business to silence a medium that encouraged rebellion and non-conformity. It was back in the 1950s that white America got its first taste of rhythm and blues, and thanks to AM deejays like Alan Freed and Wolfman Jack, radio quickly became an indelible part of the cultural landscape. But while the public embraced radio, corporate America was plotting a hostile takeover. Before long, the deejays were replaced by program directors and radio consultants - both of whom had more interest in turning a profit than sharing exciting new forms of music. In this film, viewers learn the history of the radio personalities who devoted their lives to the art of music, and the innovative musicians who transformed our perceptions of the sonic art-form.
