Etta James is best known as a robust, canvas-lunged R&B singer whose hits include “Something’s Got a Hold On Me,” “Tell Mama,” and “Fool That I Am.” But she’s also embraced pop standards, notably “At Last,” the 1961 Chess recording of which was prominently featured in several ’90s commercials and film scores. A 1993 inductee into the Rock and Roll Hall of Fame, James switched gears a year later with Mystery Lady, a tribute to Billie Holiday that received the 1995 Best Jazz Vocal Grammy. She mines the same vein in her new Private Music release, Blue Gardenia, a 13-song collection of songs identified with Dinah Washington (“This Bitter Earth” and the title composition), Julie London (“Cry Me a River”), Holiday (“My Man,” “He’s Funny That Way”), and other legendary singers. James belts and croons tonight at 7:30 p.m. at the Birchmere, 3701 Mount Vernon Ave., Alexandria. $39.50. (703) 549-7500. (JES)
