Here is the label statement: Currently touring in support of her critically-acclaimed and Grammy-nominated "Black Cadillac" album, singer/songwriter/ author Rosanne Cash has announced that she will cancel her four remaining concerts this year in order to undergo brain surgery at New York Presbyterian Hospital for a rare but benign condition Rosanne is expected to make a full recovery and will return to the studio to complete the recording of her debut for Manhattan Records. Ms. Cash will also resume her live performance schedule in the spring and will complete a new book to be published by Viking in early 2009.
