Look to the south for the sources of this Montreal roots band's flavorful folk sound. Mississippi Fred McDowell's earthy gospel blues ("Jesus Is on the Main Line") and Big Mama Thornton's gutbucket blues ("Everything Gonna Be Alright") helped establish their communally gritty sound. Dr. John ("Jump Sturdy") is like a mysterious, slightly befuddled uncle who adds bayou voodoo to their stew.
