Imagine The Dubliners sharing a pint of stout with The Pogues. Then you'll get an idea of the Dropkick Murphys' temperament. If the sextet is deeply inspired by the Irish folk tradition with banjo, accordion and bagpipes, they turn it upside down with the raw energy of punk, delivering a Finnegan's Wake that's more uppercut than gentle refrain. It was with I'm Shipping Up to Boston, borrowed by Scorsese for The Departed, that the Murphys made their mark. To experience one of their concerts is to be plunged into the tumultuous poetic ambiance of a pub on a St. Patrick's night. You've been warned.
