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.

Harry Lillis "Bing" Crosby (May 3, 1903 – October 14, 1977) was an American singer and actor. Crosby's trademark bass-baritone voice made him one of the best-selling recording artistes of the 20th century, with over half a billion records in circulation.

A multimedia star, from 1934 to 1954 Bing Crosby was a leader in record sales, radio ratings and motion picture grosses. His early career coincided with technical recording innovations; this allowed him to develop a laid-back, intimate singing style that influenced many of the popular male singers who followed him, including Perry Como,Frank Sinatra, and Dean Martin. Yank magazine recognized Crosby as the person who had done the most for American G.I. morale during World War II and, during his peak years, around 1948, polls declared him the "most admired man alive," ahead of Jackie Robinson and Pope Pius XII. Also in 1948, the Music Digest estimated that Crosby recordings filled more than half of the 80,000 weekly hours allocated to recorded radio music.

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]}
