Celtic and Irish sounds form the foundation of an incredible amount of music, from folk to country to the convivial ruckus of punk. Not all the artists here are traditionalists, but all of them have embraced the warmth and down-to-earthness that make the music so comforting. Rustic, real, tender but strong, this is the sound of Celtic traditions being carried forward. Our editors update picks here regularly, so if you hear something you like, add it to your library.
