Roberta Flack’s 11 Essential Songs

At a New York concert in 1997, Roberta Flack referred to her voice as a “blessed instrument.” For generations of listeners it was just that, a spellbinding force that could be cool, or luxurious, or swell with suggestive power, often in the same song.

Flack, who died on Monday at 88, began her career as a schoolteacher with a solid grounding in both classical music and Black church singing. She ended up one of the supreme voices of the 1970s, scoring multiple No. 1 hits that established her as a star of interpretive pop-soul, capable of stunning radio listeners and critics alike.

She was a master of the revelatory reinvention. Her first hit, “The First Time Ever I Saw Your Face,” was originally a folk ballad by Ewan MacColl. Peggy Seeger’s 1957 recording of it is a brisk, warbling take with arpeggiated acoustic guitar — a classic example of the kind of carefree-songbird tunes from the early folk revival. In Flack’s hands it is slow, stirring eroticism, with a controlled range of vocal dynamics that moves from whisper-delicate to a kind of power that feels like a carnal memory.

She did it again in 1973 with “Killing Me Softly With His Song” — originally by Lori Lieberman, another folkie — which Flack transformed into a hypnotic meditation. Two decades later, Lauryn Hill and the Fugees shifted its shape again with their own remake.

With those tracks, Flack became the first artist to take record of the year at the Grammy Awards two consecutive times, with “The First Time” winning in 1973 and “Killing Me Softly” in 1974.

Those are just two of Flack’s most familiar recordings, in a career that also included hit collaborations with singers like Donny Hathaway and Peabo Bryson, and later explorations into jazz standards. Here are 11 of her essential tracks.
