II-New Orleans Jazz & Heritage Festival:
The New Orleans Jazz & Heritage Festival, or as the locals call it, Jazz Fest, is the celebration of the unique culture and heritage of New Orleans and Louisiana. The Jazz Fest is usually held in the French Quarter of New Orleans.
Over the years, Jazz Fest has received many honors, including being named the Festival of the Year four times by Pollstar magazine. The Wall Street Journal says Jazz Fest “showcases a wider, deeper line-up of essential American musical styles than any festival in the nation”, and Life magazine has called Jazz Fest “the country’s very best music festival”.
The festival has always blended in a wide mix of internationally renowned guests, among them: Aretha Franklin, Miles Davis, Bob Dylan, Ella Fitzgerald, Dizzy Gillespie, Santana, Sarah Vaughan, Paul Simon, Jimmy Buffett, Max Roach, B.B. King, and many, many others.
