Decca Records began as a British record label established in 1929 by Edward Lewis. Its U.S. label was established in late 1934; however, owing to World War II, the link with the British company was broken for several decades.

The British label was renowned for its development of recording methods, while the American company developed the concept of cast albums in the musical genre. Both wings are now part of the Universal Music Group which is owned by Vivendi, a media conglomerate headquartered in France. The American Decca label was the foundation label which evolved into UMG.

The name "Decca" dates back to a portable gramophone called the "Decca Dulcephone" patented in 1914 by musical instrument makers Barnett Samuel and Sons. That company was eventually renamed The Decca Gramophone Co. Ltd. and then sold to former stockbroker Edward Lewis in 1929. Within years, Decca Records Ltd. was the second largest record label in the world, calling itself "The Supreme Record Company". The name "Decca" was coined by Wilfred S. Samuel by merging the word "Mecca" with the initial D of their logo "Dulcet" or their trademark "Dulcephone." Samuel, a linguist, chose "Decca" as a brand name as it was easy to pronounce in most languages.

Ella Jane Fitzgerald (April 25, 1917 – June 15, 1996), also known as the "First Lady of Song", "Queen of Jazz", and "Lady Ella", was an American jazz and song vocalist. With a vocal range spanning three octaves (D♭3 to D♭6), she was noted for her purity of tone, impeccable diction, phrasing and intonation, and a "horn-like" improvisational ability, particularly in her scat singing.

Fitzgerald was a notable interpreter of the Great American Songbook. Over the course of her 59-year recording career, she was the winner of 13 Grammy Awards and was awarded the National Medal of Arts by Ronald Reagan and the Presidential Medal of Freedom by George H. W. Bush.

Fitzgerald was born in Newport News, Virginia, the child of a common-law marriage between William and Temperance "Tempie" Fitzgerald. The pair separated soon after her birth and she and her mother went to Yonkers, New York, where they eventually moved in with Tempie's longtime boyfriend, Joseph Da Silva. Fitzgerald's half-sister, Frances Da Silva, was born in 1923. She and her family were Methodists and were active in the Bethany African Methodist Episcopal Church and she regularly attended worship services, Bible study, and Sunday School.

Louis Armstrong (August 4, 1901 – July 6, 1971), nicknamed Satchmo or Pops, was an American jazz trumpeter and singer from New Orleans, Louisiana.

Coming to prominence in the 1920s as an "inventive" cornet and trumpet player, Armstrong was a foundational influence in jazz, shifting the music's focus from collective improvisation to solo performance. With his instantly recognizable deep and distinctive gravelly voice, Armstrong was also an influential singer, demonstrating great dexterity as an improviser, bending the lyrics and melody of a song for expressive purposes. He was also greatly skilled at scat singing (vocalizing using sounds and syllables instead of actual lyrics).

Renowned for his charismatic stage presence and voice almost as much as for his trumpet-playing, Armstrong's influence extends well beyond jazz music, and by the end of his career in the 1960s, he was widely regarded as a profound influence on popular music in general. Armstrong was one of the first truly popular African-American entertainers to "cross over," whose skin-color was secondary to his music in an America that was severely racially divided. It allowed him socially acceptable access to the upper echelons of American society that were highly restricted for a black man. While he rarely publicly politicized his race, often to the dismay of fellow African-Americans, he was privately a strong supporter of the Civil Rights movement in America.^{[citation needed]}

Ernest Dale Tubb (February 9, 1914 – September 6, 1984), nicknamed the Texas Troubadour, was an American singer and songwriter and one of the pioneers of country music. His biggest career hit song, "Walking the Floor Over You" (1941), marked the rise of the honky tonk style of music. In 1948, he was the first singer to record a hit version of "Blue Christmas", a song more commonly associated with Elvis Presley and his mid-1950s version. Another well-known Tubb hit was "Waltz Across Texas" (1965), which became one of his most requested songs and is often used in dance halls throughout Texas during waltz lessons. Tubb recorded duets with the then up-and-coming Loretta Lynn in the early 1960s, including their hit "Sweet Thang". Tubb is a member of the Country Music Hall of Fame.

Tubb was born on a cotton farm near Crisp, in Ellis County, Texas (now a ghost town). His father was a sharecropper, so Tubb spent his youth working on farms throughout the state. He was inspired by Jimmie Rodgers and spent his spare time learning to sing, yodel, and play the guitar. At age 19 he took a job as a singer on San Antonio radio station KONO-AM. The pay was low so Tubb also dug ditches for the Works Progress Administration and then clerked at a drug store. In 1939 he moved to San Angelo, Texas and was hired to do a 15-minute afternoon live show on radio station KGKL-AM. He drove a beer delivery truck in order to support himself during this time, and during World War II he wrote and recorded a song titled "Beautiful San Angelo".

Loretta Lynn (born Loretta Webb April 14, 1932), is an American country music singer-songwriter, author and philanthropist. Born in Butcher Hollow, near Paintsville, Kentucky in Johnson County to a coal miner father, Lynn married at 15 years old, was a mother soon after, and moved to Washington with her husband, Oliver Vanetta Lynn, Jr. (1926–1996), nicknamed "Doo". Their marriage was sometimes tumultuous; he had affairs and she was headstrong. Their experiences together became inspiration for her music.

On her 21st birthday, Lynn's husband bought her a $17.00 Harmony guitar. She taught herself to play and when she was 24, on her wedding anniversary, Doo encouraged her to become a singer. She learned the guitar better, started singing at the Delta Grange Hall in Washington State with the Pen Brothers' band, The Westerners, then eventually cut her first record in February, 1960. She became a part of the country music scene in Nashville in the 1960s, and in 1967 charted her first of 16 number-one hits (out of 70 charted songs as a solo artist and a duet partner) that include "Don't Come Home A' Drinkin' (With Lovin' on Your Mind)", "You Ain't Woman Enough", "Fist City", and "Coal Miner's Daughter". She focused on blue collar women's issues with themes of philandering husbands and persistent mistresses, and pushed boundaries in the conservative genre of country music by singing about birth control ("The Pill"), repeated childbirth ("One's on the Way"), double standards for men and women ("Rated "X""), and being widowed by the draft during the Vietnam War ("Dear Uncle Sam"). Country music radio stations often refused to play her songs. Nonetheless, she became known as "The First Lady of Country Music" and continues to be one of the most successful vocalists of all time.
