1973 in jazz:

Sarah Lois Vaughan (March 27, 1924 – April 3, 1990) was an American jazz singer, described by Scott Yanow as having "one of the most wondrous voices of the 20th century."

Nicknamed "Sailor" (for her salty speech), "Sassy" and "The Divine One", Sarah Vaughan was a Grammy Award winner. The National Endowment for the Arts bestowed upon her its "highest honor in jazz", the NEA Jazz Masters Award, in 1989.

Biographies of Vaughan frequently stated that she was immediately thrust into stardom after a winning Amateur Night performance at Harlem's Zeus Theater. In fact, the story that biographer Renee relates seems to be a bit more complex. Vaughan was frequently accompanied by a friend, Doris Robinson, on her trips into New York City. Sometime in the fall of 1942 (when Sarah was 18 years old), Vaughan suggested that Robinson enter the Apollo Theater Amateur Night contest. Vaughan played piano accompaniment for Robinson, who won second prize. Vaughan later decided to go back and compete herself as a singer. Vaughan sang "Body and Soul" and won, although the exact date of her victorious Apollo performance is uncertain. The prize, as Vaughan recalled later to Marian McPartland, was US$10 and the promise of a week's engagement at the Apollo. After a considerable delay, Vaughan was contacted by the Apollo in the spring of 1943 to open for Ella Fitzgerald.

Lynn Taitt (June 22, 1934 – January 20, 2010) was a reggae guitarist born in San Fernando, Trinidad and Tobago, closely associated with Jamaican rocksteady music.

He was born Nerlynn Taitt, in San Fernando, Trinidad where, before taking up the guitar aged 14, he got his start as a musician playing in local steel drum bands. He formed his own band, which was booked by Byron Lee to perform at the 1962 independence celebrations in Jamaica. Taitt decided to stay in Jamaica, living in Kingston, and played in a number of bands including The Sheiks, The Cavaliers, and The Comets, and worked with Baba Brooks, The Skatalites and Tommy McCook and the Supersonics. The most successful of his groups was The Jets, formed in 1966 and which included Hux Brown, Headley Bennett, Hopeton Lewis, Gladstone Anderson, and Winston Wright. Taitt's guitar style was inventive and unconventional, with a sharp percussive sound that accented the rocksteady beat. Lynn Taitt and the Jets played on hundreds of recording sessions for Jamaican producers such as Bunny Lee, Duke Reid, Joe Gibbs, Coxsone Dodd, and Sonia Pottinger, often performing up to five sessions a day. Their recording of "Take It Easy" was one of the first rocksteady singles and it reached number one in the Jamaican singles chart.

Gene Russell (1932-1981) was an American pop, jazz, and soul keyboardist who played acoustic and Fender Rhodes.

He is mainly known for the albums he released on Black Jazz Records.

Soft Machine were an English rock band from Canterbury, named after the book The Soft Machine by William S. Burroughs. They were one of the central bands in the Canterbury scene, and helped pioneer the progressive rock genre. Though they achieved little commercial success, they are considered by Allmusic to be "one of the more influential bands of their era, and certainly one of the most influential underground ones."

Soft Machine (billed as The Soft Machine up to 1969) were formed in mid-1966 by Robert Wyatt (drums, vocals), Kevin Ayers (bass, guitar, vocals), Daevid Allen (guitar) and Mike Ratledge (organ) plus, for the first few gigs only, American guitarist Larry Nowlin. Allen, Wyatt and future bassist Hugh Hopper had first played together in the Daevid Allen Trio in 1963, occasionally accompanied by Ratledge. Wyatt, Ayers and Hopper had been founding members of the Wilde Flowers, later incarnations of which would include future members of another Canterbury band, Caravan.
