Jazz fans who complain about not hearing enough jazz in Cassandra Wilson's eclectic sound, which has increasingly tilted toward pop and blues, will find ample rewards in this collection of her (relatively) straight-ahead efforts from the late '80s. Drawing from four albums for the JMT label, it charts her steady growth away from Brooklyn's electric, funk-based M-Base school and into an earthier, more personal approach. Going to school herself on Betty Carter's elastic time feel and unhurried rhythms, she avoids predictability on songs such as "'Round Midnight" and a wordless rendering of Billy Strayhorn's "Chelsea Bridge." There's less interest in her handling of earlier standards such as "I'm Old Fashioned" and "Blue Skies," which lack depth, but never any lack of attractiveness. --Lloyd Sachs
