Chicago-based Arranmore breaks fresh musical ground by combining the very best of Celtic, folk, nation and modern genres to create its own exclusive sound. Gorgeous harmonies and exceptional musicianship travel such songs because the cult traditional “South Part Irish,” the haunting initial historic “Illinois & Michigan Canal,” the original Irish “Areas of Athenry” as well as the country-steeped “Americana.” Whether its whimsy or background, a rouser or perhaps a thought-provoking ballad, few perform them much better than Arranmore. The group contains Bob Keck, Kevin O’Donnell, Gerry Aylward, Brian Murphy, and Kirk Rende.
