The Big Band Swing Jazz Festival in New York is an annual New York City multi-stage marathon showcasing traditional New Orleans jazz in the big band swing era, as well as Manoosh jazz and ragtime. Launched in 2013 as a one-day celebration for New York City's hot jazz and swing communities, the festival has expanded its mission to include year-round presentations and promotion of traditional jazz through a variety of collaborations and partnerships, including curating and co-hosting special programs at Central Park's SummerStage, jazz at Lincoln Center and Symphony Space, as well as curating and hosting the annual dedicated Hot Jazz scene at New York's Winter Jazzfest. The festival initiated a number of original projects and contributed to the creation of a number of new groups such as Gotham Kings, Gotham SophistiCats and the Jazz Band of the Mahogany Hall Pleasure Society.
