Karan Casey, says the Associated Press, has "a voice so beautiful, it's almost impossible to avoid falling under her spell." The former lead vocalist of the Irish supergroup Solas grew up amid Irish traditional music in Ballyduff Lower, County Waterford, and few can touch her when it comes to a traditional ballad. But her sound is flavored with contemporary influences as well. John Doyle is among the most talented and innovative musicians to come out of Ireland in recent years, an extraordinary acoustic guitarist as well as an accomplished singer and songwriter. They're coming together to Michigan with a new album, "Exiles Return," that sounds like the absolute state of the art in contemporary Irish music.
