Rosanne Cash [ tickets ] has penciled in more live dates as she continues her roadwork behind last year's "Rules of Travel."

The singer/songwriter, who is currently on break, is due to resume touring with a July 23 show in Atlanta, and has also added to her itinerary stops in Boulder, CO; Seattle; Austin, TX; Reno, NV; and Chicago. The shows help fill the cracks in a loose-knit schedule that includes dates as far off as next January. Details are shown below.

Though "Rules of Travel" didn't surface until March of 2003, Cash--along with her husband, producer/songwriter/guitarist John Leventhal--began working on the set in 1998, but got derailed by a pregnancy and a polyp on her vocal chords.

"I lost my voice," she said in a statement. "Completely, for two and a half years. Some days I couldn't speak."

Cash went on to say that she and Leventhal shelved the project, and she assumed that her voice would return after she gave birth.

"I wasn't too worried in the beginning, but after I gave birth and still didn't have my voice back, I started getting anxious. It turned into an identity crisis. I started thinking about who I was without my voice. ... And I realized it had become a central part of my identity, and that I liked it, and now who was I without it?"

Cash worked with a voice therapist, and eventually was able to begin singing again.

Included on "Rules of Travel" is the cut "September When It Comes," on which Cash duets with her father, the late Johnny Cash [ tickets ], who died just weeks after the album was released.

"He was in bad health, he got very ill for a while," Cash recalled of her father during the period when she resumed work on the album. "... So I called him--I was going down to Nashville anyway--and I said, 'Dad, I'm gonna bring the tape, and if you're feeling well enough when I'm down there ....' He said, 'I can't promise, but if I feel well enough I will.' And I could tell that morning he really didn't feel well, but he said he would do it.

"So we went over to the little studio he has in the woods," she continued. "He was getting into doing it. And then he was calling for more takes: 'No, let me try that part again!' When we finished, I said, 'Dad, it's beautiful, you sound great.'"
