In honor of the St. Patrick's Day season, we've assembled 6 1/2 hours of on-demand music by some of our favorite Irish musicians. You'll hear a mix of familiar and new artists, including Mary Black, Danu, John Doyle, Donal Lunny, Connie Dover, Andy Irvine, Planxty, Grada, The Chieftains (of course)... and much, much more!
