Louis Leo Prima was an American trumpeter, singer, entertainer, and bandleader. While rooted in New Orleans jazz, swing music, and jump blues, Prima touched on various genres throughout his career: he formed a seven-piece New Orleans-style jazz band in the late 1920s, fronted a swing combo in the 1930s and a big band group in the 1940s, helped to popularize jump blues in the late 1940s and early to mid 1950s, and performed frequently as a Vegas lounge act beginning in the 1950s.

Swing music is a style of jazz that developed in the United States during the late 1920s and early 1930s. It became nationally popular from the mid-1930s. The name derived from its emphasis on the off-beat, or nominally weaker beat. Swing bands usually featured soloists who would improvise on the melody over the arrangement. The danceable swing style of big bands and bandleaders such as Benny Goodman was the dominant form of American popular music from 1935 to 1946, known as the swing era, when people were dancing the Lindy Hop. The verb "to swing" is also used as a term of praise for playing that has a strong groove or drive. Musicians of the swing era include Duke Ellington, Benny Goodman, Count Basie, Cab Calloway, Benny Carter, Jimmy Dorsey, Tommy Dorsey, Woody Herman, Earl Hines, Harry James, Lionel Hampton, Glenn Miller, Artie Shaw, Jimmie Lunceford, and Django Reinhardt.
