Delia Gartrell was an American soul and blues singer-songwriter, best known for her 1960s hit songs "See What You Done Done (Hymn No. 9)" and "Fight Fire with Fire". She was born and raised in Philadelphia and began her music career as a teenager, performing in nightclubs and recording demos. Gartrell's recorded output was brief, releasing only a handful of singles and one full-length album during her career, but she left a lasting impact on the soul and blues genres. After retiring from music in the early 1980s, Gartrell worked as a nurse and died in 1991 at the age of 46.
