Shovels & Rope, “Birmingham”

Cary Ann Hearst and Michael Trent sing like old lovers, entwining their voices in close harmony one minute and shouting above one another in heated, twangy tones the next. Together, they make a rough-and-tumble kind of folk music, the kind of gorgeous, down-home stuff that Gillian Welch and David Rawlings might’ve done if they’d skipped music school and learned the ropes in roadhouses instead.
