Arguably the most wildly talented jazz singer to emerge in the 21st century, Cécile McLorin Salvant artfully updates the supple elasticity of Sarah Vaughan or Betty Carter in her own vibrant way. She's a sharp composer, addressing contemporary mores with wit and grace; her “Visions,” a duet with pianist Sullivan Fortner that channels a Stevie Wonder vibe, yearns for a world built on equality. Her pitch control is sublime, and her melodic improvising deploys phrasing both comic and theatrical; she brings feminist insouciance to Bessie Smith's “Sam Jones' Blues.” Her authoritative grasp of various traditions always sounds natural.
