Massimo Filippo Antongiulio Maria Freccia was an Italian American conductor. He had an international reputation but never held a post as music director of a major orchestra or opera house. Unusually for an Italian, he built his career around symphonic music rather than opera. For several years he was an assistant to Arturo Toscanini, whom he venerated, and he was regularly invited by Toscanini to conduct the NBC Symphony Orchestra.
