New Orleans rhythm and blues is a style of rhythm and blues that originated in New Orleans. It was a direct precursor to rock and roll and strongly influenced ska. Instrumentation typically includes drums, bass, piano, horns, electric guitar, and vocals. The style is characterized by syncopated "second line" rhythms, a strong backbeat, and soulful vocals. Artists such as Roy Brown, Dave Bartholomew, and Fats Domino are representative of the New Orleans R&B sound.

Ska is a music genre that originated in Jamaica in the late 1950s and was the precursor to rocksteady and reggae. It combined elements of Caribbean mento and calypso with American jazz and rhythm and blues. Ska is characterized by a walking bass line accented with rhythms on the off beat. It was developed in Jamaica in the 1960s when Stranger Cole, Prince Buster, Clement "Coxsone" Dodd, and Duke Reid formed sound systems to play American rhythm and blues and then began recording their own songs. In the early 1960s, ska was the dominant music genre of Jamaica and was popular with British mods and with many skinheads.
