Airs Monday, December 2 at 8 p.m. The cresting New Orleans trombonist performed at the Newport Jazz Festival on August 6. In New Orleans, jazz is a building block, a musical foundation. Troy Andrews, aka Trombone Shorty, fully embraces the future-funk and grimy rock backbeats which bring crowds to their feet. But at his core, he's also a phenomenal jazz trombonist and singer from the Tremé neighborhood.
