Maz and Bricks, a production of the estimable Irish company Fishamble, draws on many of the hallmark of Irish drama in the last quarter century. Playwright Eva O’Connor tells her story, a two-hander, with vibrant narrative monologues alternating with scenes and even a double direct address from its characters to the audience. The monologue intertwining has been a staple of Irish playwriting from Brian Friel (Faith Healer, 1979) to Conor McPherson (Port Authority, 2001). The scabrous language, elevated to poetry, is equally Irish.
