Beyond the brash punk anthems that they're known for, Flogging Molly have a bittersweet, folkish side to their music, with songs inspired by frontman Dave King's Irish upbringing. "The Son Never Shines (On Closed Doors)" is a mournful banjo ballad that King wrote after visiting his mother in Ireland, while Lucinda Williams adds grit and regret to "Factory Girls," a tune looking back at simpler, happier times.
