He had been composing chamber music, symphonies and opera since he was a teenager in Vienna. In Baton Rouge in the 1960s he conducted his opera "Serenade at Noon" at Louisiana State University. Then, in the late 80s and early 90s, excerpts from his opera "White Agony" were produced at the Komische Oper in Berlin (where Felsenstein had directed). In 1992, the Greensboro Opera produced a staged version of "White Agony" staged by his wife, Elissa Minet Fuchs, former ballerina of Ballet Russe de Monte-Carlo and the Metropolitan Opera. As well as his three operas (Serenade at Noon, The White Agony, and The Heretic), his other compositions include a symphony, a Concertino for Piano and Orchestra, Inventions for Wind Instruments, string quartets, a violin sonata, works for piano, and many songs. He directed many opera workshops notably at the Manhattan School of Music where, in 1962, he conducted the premier of Jan Meyerowitz's "Godfather Death". Both his daughter Debora Porazzi and son in law Arturo Porazzi work production roles on Broadway.
