Fletcher Henderson in the context of "Swing music"

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. 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 Fletcher Henderson and 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. Big band leaders of the swing era include Benny Goodman, Duke Ellington, Count Basie, Jimmie Lunceford, Cab Calloway, Benny Carter, Jimmy Dorsey, Tommy Dorsey, Earl Hines, Bunny Berigan, Harry James, Lionel Hampton, Glenn Miller, and Artie Shaw.

Louis Daniel Armstrong (August 4, 1901 – July 6, 1971), nicknamed "Satchmo", "Satch", and "Pops", was an American jazz and blues trumpeter and vocalist. He was among the most influential figures in jazz. His career spanned five decades and several eras in the history of jazz. Armstrong received numerous accolades including the Grammy Award for Best Male Vocal Performance for Hello, Dolly! in 1965, as well as a posthumous win for the Grammy Lifetime Achievement Award in 1972. His influence crossed musical genres, with inductions into the DownBeat Jazz Hall of Fame, the Rock and Roll Hall of Fame, and the National Rhythm & Blues Hall of Fame, among others.

Armstrong was born and raised in New Orleans. Coming to prominence in the 1920s as an inventive trumpet and cornet player, he was a foundational influence in jazz, shifting the focus of the music from collective improvisation to solo performance. Around 1922, Armstrong followed his mentor, Joe "King" Oliver, to Chicago to play in Oliver's Creole Jazz Band. Armstrong earned a reputation at "cutting contests", and his fame reached band leader Fletcher Henderson. Armstrong moved to New York City, where he became a featured and musically influential band soloist and recording artist. By the 1950s, Armstrong was an international musical icon, appearing regularly in radio and television broadcasts and on film. Apart from his music, he was also beloved as an entertainer, often joking with the audience and keeping a joyful public image at all times.

John Henry Hammond Jr. (December 15, 1910 – July 10, 1987) was an American record producer, civil rights activist, and music critic active from the 1930s to the early 1980s. As a talent scout, Hammond became one of the most influential figures in 20th-century popular music. He is the father of blues musician John P. Hammond.

Hammond sparked or advanced numerous musical careers, including those of Bob Dylan, Bruce Springsteen, Benny Goodman, Harry James, Charlie Christian, Billie Holiday, Count Basie, Teddy Wilson, Big Joe Turner, Fletcher Henderson, Pete Seeger, Babatunde Olatunji, Aretha Franklin, George Benson, Freddie Green, Leonard Cohen, Arthur Russell, Jim Copp, Asha Puthli, Stevie Ray Vaughan, Mike Bloomfield and Sonny Burke. He is also largely responsible for the revival of delta blues artist Robert Johnson's music.

Bennett Lester Carter (August 8, 1907 – July 12, 2003) was an American jazz saxophonist, clarinetist, trumpeter, composer, arranger, and bandleader. With Johnny Hodges, he was a pioneer on the alto saxophone. From the beginning of his career in the 1920s, he worked as an arranger, including writing charts for Fletcher Henderson's big band that shaped the swing style. He had an unusually long career that lasted into the 1990s. During the 1980s and 1990s, he was nominated for eight Grammy Awards, which included receiving a Lifetime Achievement Award.
