The titlePassage of Timecould refer to the eight-year gap between Liz Callaway's 2009 solo album and her previous solo album,The Beat Goes On, from a time when she was a cornerstone of producer Bruce Kimmel's Broadway-themed albums at Varese Sarabande and Fynsworth Alley. But it could also refer to the natural maturation of the golden-voiced star and the inevitable changes in her life and family.  The latter implication is revealed in some of her song choices, such as Stephen Sondheim's "Children Will Listen," Dave Grusin and Alan and Marilyn Bergman's "A Child Is Born," and a pair of Andrew Lloyd Webber songs: "The Perfect Year" fromSunset Boulevardand "Memory" fromCats, which memorializes the role Callaway occupied as probably the third-most-famous Grizabella, after Elaine Paige and Betty Buckley.  Callaway's sister, jazz chanteuse Ann Hampton Callaway, also appears in the duet "That's the Way I've Always Heard It Should Be" (Liz sings "Not That Girl" here, leading one to imagine how well-suited another song fromWicked, "For Good," would have been for the sisters).  There may be no "Meadowlark" here, but Callaway's soprano sounds as pure as ever on Stephen Flaherty and Lynn Ahrens' "Nothing to Lose (But Your Heart)" and Sondheim's "Being Alive,"  and she's in the best of hands with director-arranger Alex Rybeck and producer Tommy Krasker.  We can only hope that her next project will be not so long in the making.--David Horiuchi
