The term “Swing” is associated with the big band compositions of the 1930s-1940s that packed dance halls across the U.S. The best known composers and performers from the era include Duke Ellington, William Count Basie, Louie Armstrong, Benny Goodman, Gene Krupa, Glen Miller and Cab Calloway
Swing lost some of its popularity after WWII, and big bands for the most part folded or cut back to fewer players. Music played by small groups with as few as four pieces can swing, as do many original tunes written after the era. Swing musicians best known for their work in the 1950s and 1960s include Louis Jordan and Louis Prima.
Modern swing bands typically fall into many categories including Jazz, Blues, Dixieland and Jump Blues. As long as their music is really swinging, they generally get the real Lindy Hoppers on hand to rip it up on the dance floor.
