To those used to the reassuring regularity of mainstream pop, Moriarty might seem one of the strangest things to see on stage. They’ve played in many a strange location, from mental institutions to a ruined castle and a transatlantic ship. Although they come from Paris, they peddle ye olde folk that calls to mind verdant forests and expansive mountainside paddocks. Dressing for the genre in thrift-store-sourced rags, they rely on a couple of acoustic guitars, a harmonica, a double bass, and the tangy vocals of Rosemary Moriarty to bring to life their brand of folk and blues.
