Uilleann piper Joey, fiddler Nathan and bouzouki player Owen constitute a Boston-based traditional music power trio. Joey, a California transplant who has taken well to New England soil, is a one of America’s top home-grown pipers. Nathan hails from Minnesota, where he soaked up traditional tunes and style from County Offaly accordion legend Paddy O’Brien. Their 2016 CD Copley Street, which featured generous portions of Greek bouzouki backing from Vermonter Owen Marshall, was one of the year’s finest Irish traditional music recordings.
