For nearly three decades, James McMurtry has crafted tunes about dusty back roads, washed up high school jocks and blue-collar struggles. His rough-hewn voice lends a ragged edge to his sharp observations of the world around and the inner toils of desperate people. That he has excelled as a writer is almost to be expected. His father is the Pulitzer Prize-winning novelist Larry McMurtry (“Lonesome Dove,” “The Last Picture Show), his mother, Jo, a retired college English professor. Back on the road in support of his latest record, “Complicated Game” – which RollingStone.com has dubbed an “Americana masterpiece” – McMurtry and his band are coming to the Bartlett on Thursday. A true road warrior – he jokes he’s the only guy to ever play Miles City, Montana – McMurtry took a few minutes to speak by phone from Philadelphia. Below is an edited transcript of our conversation.
