Roberta Flack, the Grammy-winning singer and pianist whose intimate vocal and musical style on Killing Me Softly with His Song, The First Time Ever I Saw Your Face and other hits made her one of the top recording artists of the 1970s and an influential performer long after, died Monday. She was 88.

She died at home surrounded by her family, publicist Elaine Schock said in a statement. Flack announced in 2022 she had ALS, commonly known as Lou Gehrig's disease, and could no longer sing,

Little known before her early 30s, Flack became an overnight star after Clint Eastwood used The First Time Ever I Saw Your Face as the soundtrack for one of cinema's more memorable and explicit love scenes, between the actor and Donna Mills in his 1971 film Play Misty for Me. The hushed, hymn-like ballad, with Flack's graceful soprano afloat on a bed of soft strings and piano, topped the Billboard pop chart in 1972 and received a Grammy for record of the year. In 1973, she matched both achievements with Killing Me Softly, becoming the first artist to win consecutive Grammys for best record.

She was a classically trained pianist discovered in the late 1960s by jazz musician Les McCann, who later wrote that "her voice touched, tapped, trapped, and kicked every emotion I've ever known." Versatile enough to summon the up-tempo gospel passion of Aretha Franklin, Flack often favored a more reflective and measured approach.

For Flack's many admirers, she was a sophisticated and bold new presence in the music world and in the social movements of the time, her friends including the Rev. Jesse Jackson and Angela Davis, whom Flack visited in prison while Davis faced charges — for which she was acquitted — for murder and kidnapping. Flack sang at the funeral of Jackie Robinson, major league baseball's first Black player, and was among the many guest performers on the feminist children's entertainment project created by Marlo Thomas, Free to Be ... You and Me.
