Tech Sgt. Ryan Miles, left, and Senior Airman Stephanie Robinson, members of the Band of the U.S. Air Force Reserve Brass Quintet, perform in front of the USS Cairo Museum at the Vicksburg National Military Park Sunday afternoon. The quintet, which also includes a drummer, performed a set with pieces ranging from Civil War-era tunes to a rendition of “Bohemian Rhapsody.” Up to 100 people heard at least part of the hourlong concert.
