She is most often referred to as a rhythm and blues singer, and that is how she made her name in the 1950s with records like “Good Rockin’ Daddy.” She is in both the Rock and Roll Hall of Fame and the Blues Hall of Fame.
She was also comfortable, and convincing, singing pop standards, as she did in 1961 with “At Last,” which was written in 1941 and originally recorded by Glenn Miller’s orchestra. And among her four Grammy Awards (including a lifetime-achievement honor in 2003) was one for best jazz vocal performance, which she won in 1995 for the album “Mystery Lady: Songs of Billie Holiday.”
For all her accomplishments, Ms. James had an up-and-down career, partly because of changing audience tastes but largely because of drug problems. She developed a heroin habit in the 1960s; after she overcame it in the 1970s, she began using cocaine. She candidly described her struggles with addiction and her many trips to rehab in her autobiography, “Rage to Survive,” written with David Ritz (1995).
