Preservation Hall opened in 1961 to safeguard traditional New Orleans jazz. Before long the musicians playing there nightly took the show on the road, fomenting a revival of the city's most consequential music. Early on the group featured musicians active at the inception of jazz, but well into the 21st century, younger members are fluent in the traditional style, where ebullient horn lines dance in a heady mash of contrapuntal melody. They specialize in Dixieland classics like “Basin Street Blues”, but they've also applied their joyful sound to Crescent City R&B like “Go to the Mardi Gras” or Duke Ellington's swing-era staple “Mood Indigo”.
