Etta James is the greatest of all modern blues singers. Her raw, unharnessed vocals and hot-blooded eroticism has made disciples of singers ranging from Janis Joplin to Bonnie Raitt. James' pioneering 1950s hits - "The Wallflower" and "Good Rockin' Daddy" - assure her place in the early history of rock and roll alongside Little Richard, Chuck Berry and Ray Charles. "Tell Mama" from 1967 was a searing slice of upbeat Southern soul that contrasted markedly with another standout from the same sessions, the spine-chilling ballad "I'd Rather Go Blind." In concert, Etta James is a sassy, no-holds-barred performer. She's paid her dues many times over as an R&B and soul pioneer; long may she continue to shock the uninitiated.
