Members of the U.S. Army are taking over some space at UNO. To perform jazz. Nineteen musicians take the stage under the banner of the United States Army Field Band Jazz Ambassadors. This group has been around the U.S. and the world for nigh on to 45 years, in a repertoire reflecting the jazz legacy, traditional New Orleans-style, big band, bebop, latino, modern. And, of course, now and again, something more deliberately patriotic, sometimes, too, playing their own originals.
