Alfredo Antonini (1901–1983) appeared at least once every season from 1948 to 1964. Each summer, he was entrusted the task of directing a concert devoted to Italian opera arias and excerpts featuring stars from the Met. In 1954, Antonini took on three concerts, leading the José Greco Dance Company on 5 July, a symphonic concert on 6 July, and an opera night on 17 July.
