Billie Holiday was an American jazz and swing music singer. Nicknamed "Lady Day" by her friend and music partner, Lester Young, Holiday made a significant contribution to jazz music and pop singing. Her vocal style, strongly influenced by jazz instrumentalists, inspired a new way of manipulating phrasing and tempo. She was known for her vocal delivery and improvisational skills.
After a turbulent childhood, Holiday began singing in nightclubs in Harlem where she was heard by producer John Hammond, who liked her voice. She signed a recording contract with Brunswick in 1935. Her collaboration with Teddy Wilson produced the hit "What a Little Moonlight Can Do", which became a jazz standard. Throughout the 1930s and 1940s, Holiday had mainstream success on labels such as Columbia and Decca. By the late 1940s, however, she was beset with legal troubles and drug abuse. After a short prison sentence, she performed a sold-out concert at Carnegie Hall.
She was a successful concert performer throughout the 1950s, with two further sold-out shows at Carnegie Hall.
