(Published in Jackson Hole Weekly, additional content added) Get Fat this Mardi Gras Tuesday with Jackson Six When you stroll into the Silver Dollar Bar on Fat Tuesday, it will look like a narrower demographic of a scene from HBO’s television drama, “Treme,” complete with Jackson’s own trombone-led Dixieland band that brings the spirit of New Orleans alive—1,900 miles from the source. Jackson Six brings to mind the incomparable Louis Armstrong and His Hot Five, adding a contemporary edge to the swinging, stomping and syncopated beats of New Orleans traditional jazz. Grab some beads, a Mardi Gras mask, and get to the dance floor. Expect to see a lot of special guests for this show, including an extra trumpet and a guest ivory player.  Jackson Six, 7:30 to 11 p.m., Fat Tuesday at the Silver Dollar Bar. Free.
