Annie Ross was a British-American singer and actress, best known as a member of the influential jazz vocal trio Lambert, Hendricks & Ross. She pioneered the vocalese style of jazz singing, with a style described by critic Dave Gelly as "a kind of dreamy watchfulness that is a definition of 1950s hip." In 2010, she was named a Jazz Master by the National Endowment for the Arts.
Kenneth Tynan, who wrote liner notes for Ross, called her "a fallen angel" who "moves us and then brushes off our sympathy with a shrug of her lips."
