Allen Richard Toussaint was an American musician, songwriter, arranger, and record producer. He was an influential figure in New Orleans rhythm and blues from the 1950s to the end of the century, described as "one of popular music's great backroom figures." Many musicians recorded Toussaint's compositions. He was a producer for hundreds of recordings: the best known are "Right Place, Wrong Time", by longtime friend Dr. John, and "Lady Marmalade" by Labelle.

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.
