A chief voice in Phil Spector’s ’60s singles factory, Love has found success since as a singer, a late-night TV favorite, a documentary subject and an actor (in Lethal Weapon and Broadway’s Hairspray). Her esteem among other artists has only grown, and deservedly so: No one sings like she sings. Her latest album, 2015’s Introducing Darlene Love, includes songs written for her by Bruce Springsteen and Elvis Costello. At this annual B.B. King gig, she celebrates the holidays as only the venerated singer can.
