Music is something we have always had to be proud of in this country, with rock music being a particular forte of ours. This documentary tells the story of how rock music helped bring about change for Ireland over 40 years, and how the sounds that emerged were grounded in the musical traditions of Ireland's two main cities - Belfast and Dublin. It looks all the way back to the showbands of the late fifties through to the modern day, and examines how the harder sounds of Belfast merged with the more folk-centric traditions of Dublin. It also looks at some of the key Irish musicians of the last fifty years and how they were influenced by the political, social and cultural climate of their surroundings. Featuring contributions from U2, Sinead O'Connor and Bob Geldof.
