Dinah Washington was one of the premier vocal stylists in American popular music from the 1940s through the early ’60s. She came of age as the music industry was beginning to loosen its arbitrary assumptions about genre and audience (in 1949, Billboard started calling its “race records” chart its R&B chart), and her wide stylistic range took every advantage of that development. Washington could sing elegant jazz, 12-bar blues both bawdy and bereft, proto–rock ’n’ roll romps, and lush ballads.
