Preservation Hall Jazz Band is a New Orleans treasure. The Dixieland jazz group, which is currently a septet, has, like the city it reps and the aural artform it plies, undergone evolutions aplenty throughout its 50-year history, masterfully toeing the line between honoring the past and inventing the future. In the live setting, the inventive crew doesn’t play a song the same way twice, always pushing themselves to make new connections to the music and the audience. This weekend, the band, a beacon of history and classic American song, presents its Creole Christmas, a special set bursting with all the magic of the holidays in the Crescent City. Featuring both faithful and updated takes on old favorites, as well as originals and rare treats, the show promises to be just the ticket to kickstart your holiday season.
