In 1999 he co-founded and coordinated the "Festa della Musica", a showcase of classical, jazz and world music held in Milan, and four years later he managed the Ravello Festival. In 2007 Lorenzo Ferrero was appointed to the board of directors and elected vice-president of SIAE, the Italian Authors and Publishers Association. That same year he published the "Manuale di scrittura musicale", a manual which describes the basic rules of correct and elegant music writing from the orthographic as well as the graphic point of view, which is addressed to all composers, musicologists, teachers, students and copy-editors in need of practical advice. In 2008 he translated, edited and published "Lo studio dell'orchestrazione", the Italian edition of Samuel Adler's "The Study of Orchestration", a landmark orchestration manual. Lorenzo Ferrero has been professor of composition at Milan Conservatory from 1980 to 2016. His teaching appointments also include positions at St. Mary's College of Maryland and LUISS Business School, a division of LUISS Guido Carli University of Rome. Moreover, as member of the Italian National Union of Composers, Librettists and Authors he co-founded ECSA, the European Composer and Songwriter Alliance, and between 2011 and 2017 he was president of CIAM, the International Council of Music Authors. In 2017, he was appointed honorary president of CIAM. Lorenzo Ferrero was described in "The New Grove Dictionary of Opera" as "the most successful opera composer of his generation in Italy" and in "The New Penguin Opera Guide" as "a principal exponent of the neo-tonal tendencies common to a number of Italian composers of his generation, who has championed a brand of narrative music-theatre that aims to capture a wider audience than that achieved by the heirs of the modernist tradition." In addition to the original works listed below, Lorenzo Ferrero completed the orchestration of the third version of the opera "La rondine" by Giacomo Puccini, which was subsequently premiered at Teatro Regio di Torino on 22 March 1994. With a group of six other Italian composers he wrote the "Requiem per le vittime della mafia", a collaborative composition for soloists, choir and orchestra on an Italian text by Vincenzo Consolo. The requiem was first performed in the Palermo Cathedral on 27 March 1993. Furthermore, he wrote the music for the Sestriere Alpine World Ski Championships opening ceremony of 1997 including the official anthem, incidental music for stage productions, and a film score.
