New Orleans dances Latin on top of a music city that already had its own social-dance traditions for two centuries. The Caribbean cultural ties — Cuban, Haitian, Dominican — go back to before the United States bought the city, and the modern Latin scene carries that history quietly. Frenchmen Street, the Marigny, and the Bywater run the weekly floors.

Frenchmen Street and the French Quarter hold the central Wednesday and weekend salsa nights — live music is the default, recorded DJ sets the exception. The Marigny and Bywater run the newer bachata-sensual socials in converted warehouses. Mid-City and the West Bank have the Hispanic-community floors and studio circuit. New Orleans summers are wet and serious; outdoor socials are rare.

If a band is playing, the night is worth more than two recorded-DJ socials elsewhere. New Orleans musicians improvise the salsa floor in real time — the call-and-response between the band and the dancers is the city's particular gift. Listen as much as you dance.
