Task: Question Generation
Input (English): Music of New Orleans -- The African influence on New Orleans music can trace its roots at least back to Congo Square in New Orleans in 1835, when slaves would congregate there to play music and dance on Sundays. African music was played as well as local music, including that of local white composers, such as Louis Moreau Gottschalk. Along with European musical forms that were popular in the city, including the brass band traditions, the cultural mix laid the groundwork for the New Orleans musical art forms to come.
