Johnny Cash's daughter has a voice that floats like smoke. But she can also turn it up and belt it out, especially when she's dipping into some of that New Traditional country. Cash's more glossily produced songs about her failed marriage to Rodney Crowell don't really do her justice; the plastic production tends to make her sound like any other New Country singer with a famous daddy. It's when we get to hear the real Rosanne, like on 1981's Seven Year Ache that the twang really becomes her.
