There was a time when most jazz clubs in cities like New York, Chicago, New Orleans, and Kansas City were “mobbed up.” Throughout the century, this model spread to other cities on the coasts (especially in Los Angeles) and in the Midwest (St. Louis, Detroit, Denver, and others). In the Nevada desert, an entire city was founded on the relationship between jazz and the underworld (Las Vegas), and the model was transported beyond the boundaries of the United States to Havana, Cuba, in an audacious attempt by the mob to go international.
