When you think New Orleans jazz, what comes to mind? Lively horns. Punctuating trombone. Saxophone runs. Syncopated keyboard. All these stir together in harmonies that both tap your toes and make you sway. For a mix as varied and tasty as authentic jambalaya, try Treme: Music from the HBO Original Series, Season 1. The very soul of post-Katrina “New Awlins” is set to music with an amazing collection of artists including Dr. John, John Boutté, Kermit Ruffins, Irma Thomas, and Li’l Queenie and the Percolators. With a vitality that can barely be contained, the album builds a diverse carnival of music that begs you to jump to your feet and join the parade.
