With a title in the form of a pleonasm, *Swingin’ Easy* demonstrates, at the beginning of her phenomenal career, the extraordinary qualities of Sarah Vaughan. With several octaves at her disposal, an emotional velvetiness, and disconcerting ease in improvisation, one of the greatest performers in jazz history gracefully glides through a classic repertoire, which she revitalizes with her rare talent, embodying the most uninhibited and controlled scat there is.
