Delois Barrett Campbell

Delois Barrett Campbell, who died yesterday aged 85, was a member of the award-winning Barrett Sisters trio, who electrified audiences with their powerful gospel harmonies.

The Sisters, raised on Chicago's South Side and coached to sing by an aunt, grew up to become what the music critic Howard Reich called "the greatest female trio in gospel history".

Delois Barrett began singing at Chicago's Pilgrim Baptist Church, and first joined the Roberta Martin Singers, who also started there.

The Barrett Sisters practised blending their voices on religious and secular songs: the Andrews Sisters were an influence. They recorded their first album, Jesus Loves Me, in the mid-1960s, while new generations discovered them when they appeared in the 1982 documentary Say Amen, Somebody.
