In her late fifties and early sixties Ella Fitzgerald's voice took on darker coloration and an occasional slight huskiness. She also developed a vibrato on low notes. At the same time, she seemed to begin paying closer attention to the meaning of the lyrics of the songs she sang. Together, those elements resulted in an enhancement of her womanly qualities over the girlish purity for which she was known. What did not change was what had always endeared Ella to audiences and her fellow musicians, her unfailing sense of time. The changes produced a singer who swung as hard as ever but whose work had new depth and wisdom. This collection is largely made up of what used to be called rhythm ballads, and it brings us Ella Fitzgerald in the glory of her maturity, sounding as if she's having the time of her life. And swinging.
