Anita O'Day (October 18, 1919 – November 23, 2006) was an American jazz singer.
O'Day, along with Mel Tormé, is often grouped with the West Coast cool school of jazz. Like Tormé, O'Day had some training in jazz drums (courtesy of her first husband Don Carter); her longest musical collaboration was with John Poole, a skilled jazz drummer who was known for his explosive drum solos. While maintaining a central core of hard swing, O'Day's considerable skills in improvisation of rhythm and melody put her squarely among the pioneers of bebop; indeed, a staple of her live act in the 1950s was a smooth cover of "Four" by Miles Davis.
O'Day always maintained that the accidental excision of her uvula during a childhood tonsillectomy left her incapable of vibrato, as well as unable to maintain long phrases. That botched operation, she claimed, forced her to develop a more percussive style based on short notes and rhythmic drive. However, when she was in good voice she demonstrated surprising skill at stretching long notes with strong crescendos and a telescoping vibrato, e.g. her stunning live version of "Sweet Georgia Brown" at the 1958 Newport Jazz Festival, captured in Bert Stern's film Jazz on a Summer's Day . Noteworthy is that one can hear on her records that her prominent upper teeth sometimes lead to her articulation of the "B" and the "P" as a "W" (e.g.. Sweet Georgia "Wrown").
O'Day's long-term problems with heroin and alcohol addiction and her often erratic behavior related to those problems earned her the nickname "The Jezebel of Jazz".
Born in a broken home in Chicago O'Day took the first chance to leave home when, at age 14, she became a contestant in the popular Walk-a-thons as a dancer. She toured with the Walk-a-thons circuits for two years, occasionally being called upon to sing. In 1934, she began touring the Midwest as a marathon dance contestant and singing "The Lady in Red" for tips.
While performing at the Off Beat, she met Gene Krupa, who promised to call her if Irene Daye, his current vocalist, left his band. In 1939 she was hired as vocalist for Miller's Quartet, which had a stay at the Three Deuces club in Chicago.
The call from Krupa finally came in early 1941. Of the 34 sides she recorded with Krupa, it was "Let Me Off Uptown", a novelty duet with Roy Eldridge, that became her first big hit. That year, Down Beat named O'Day "New Star of the Year". In 1942, she appeared with the Krupa band in two "soundies" (short musical films), singing "Thanks for the Boogie Ride" and "Let Me Off Uptown". The same year Down Beat readers voted her into the top five big band singers. O'Day came in fourth, with Helen O'Connell first, Helen Forrest second, Billie Holiday third, and Dinah Shore fifth. O'Day married again in 1942, this time to golf pro and jazz fan Carl Hoff.
