From Medieval Wexford to Midtown Manhattan Larry Kirwan tells the story of Irish music to a backdrop of war, social upheaval and revolution. From Viking invader to Sean O'Riada, Oliver Cromwell to Rory Gallagher, James Connolly to Van Morrison in a clash of uilleann pipes, armalites and electric guitars. The story moves with the Diaspora to The Pogues' London, Dropkick Murphys' Boston and Black 47's New York City. Pulsing, passionate, occasionally tragic - through the eyes of an insider.
