Singer/songwriter Rosanne Cash [ tickets ] has added new dates to her current outing, which has found her touring on and off since last December in support of her latest album, 2006's "Black Cadillac."

Cash, whose next date is scheduled for March 18 in Nashville, TN, has tacked on new shows in California, the Midwest and the Northeast as she continues to casually expand her itinerary, which now runs into September. Details are included below.

"Black Cadillac," which hit stores last January, explores themes of grief and acceptance, a process Cash has become familiar with in her personal life, losing her father (Johnny Cash), mother (Johnny Cash's first wife, Vivian Liberto) and step-mother (June Carter Cash) during the past two years.

The album's title track was written six weeks before June Carter's death, at a point when no one knew she was even ill, according to Cash in her online bio, who calls the song "foreboding."

"I've always found that songs can be postcards from your future," she said. "I felt that I had to fit everything else around that song. That was the theme."

The album was co-produced by her husband, John Leventhal (Shawn Colvin, David Crosby), with Bill Bottrell (Sheryl Crow, Shelby Lynne).

"I'm still getting perspective on it," she said of the recent deaths in her family and the making of the new album. "I feel a little exhausted, and I still feel so many of the emotions that are in those songs. Some of them will never go away."

"Black Cadillac" received wide critical acclaim, with the album landing on many critics' year-end Top 10 lists, including the New York Times' Jon Pareles and the Billboard 2006 Year In Music critics roundup.
