Numerous studies examine Irish traditional music influencing old-time music, but few examine the influence of old-time on contemporary Irish. As our societies become more global, folk music travels faster and becomes more open to influence. Thes influences can be heard in the music of “Alfi” and “Lankum,” two ensembles steeped in Irish traditional music. This study defines common musical elements of old-time and examines the use of those elements in two recordings: Alfi’s, “Jubilee” and Lankum’s, “The Old Man from Over the Sea.” Much of my data comes from interviews with Irish and American musicians and my own professional knowledge, gaining a deeper understanding of the musical decisions made by members of Alfi and Lankum. This study adds to the formal literature relating to old-time and Irish traditional music. More importantly, it helps fill a gap in the literature by adding to the discussion of the dissemination of traditional music.
