One of R&B's earliest divas, LaVern Baker could grab hold of a song and belt it out with the best of them, whether she was singing bouncy, up-tempo rock & roll or bluesy torch ballads.

Baker's contributions to the rockin' and rollin' wing of '50s R&B were in a class with Atlantic labelmates Ruth Brown and the Clyde McPhatter-era Drifters, as the stellar 20-track compilation Soul on Fire: The Best of LaVern Baker proves.

Baker had a muscular delivery and a commanding personality on record, so much so that her ravishing visual appeal wasn't even necessary (though it certainly didn't hurt).

Here she bellows and growls her way through rock & roll standards like "Tweedlee Dee" (her first big hit), the oft-covered "Jim Dandy" (her only R&B chart-topper), and "See See Rider," not to mention Leiber & Stoller's gospel pastiche "Saved." But Baker was equally powerful on her slow numbers, turning in positively smoldering performances on the classics "Soul on Fire," "Play It Fair," "I Cried a Tear" (her biggest pop hit), and "I Waited Too Long," among others.

Baker isn't as much of a household name as she probably ought to be, but Soul on Fire is required listening for anyone interested in the first waves of R&B and rock & roll.
