If you've ever walked into a bar to hear a crashing, raucous assault of breakneck Irish punk, you've likely had a taste of Dropkick Murphys. With a furious blend of Celtic melody, snarling hardcore and uncontainable rock ‘n' roll energy, they start pub sing-alongs that are as riotous as they are catchy. Tunes like the sailor anthem “I'm Shipping Up to Boston” will catch you raising a glass and belting the chorus, while “The Warrior's Code” conjures up blurry but unforgettable St. Patrick's Days.
