year, Vacchi directed the Atelier Opéra en création at the Aix-en-Provence Festival, where his works were performed between 2014 and 2015, among which Dai calanchi di Sabbiuno conducted by P.Järvi in a concert dedicated to the memory of P.Chereau. In 2016 his ninth opera came out, Lo specchio magico, based on a text by Aldo Nove (staged at the Maggio Musicale Fiorentino, conducted by John Axelrod) and Vencidos for voice and orchestra commissioned by the Festival Internacional Cervantino, in Mexico, for the Miguel de Cervantes celebrations. In 2018 the Teatro San Carlo put on Eternapoli, at the request of Toni Servillo. Again in 2018, after the Concerto for violoncello at Petruzzelli di Bari, the Concerto for violin Natura naturans had its European première at the Opera of Budapest and its American première at the Carnegie Hall in New York, (conductor Balázs Kocsár, soloist Haruka Nagao). In February 2019 the Orchestra laVerdi of Milan devoted four monographic concerts to him, including the Italian première of Natura naturans. Works of social commitment Riccardo Muti conducted Diario dello Sdegno (Teatro alla Scala, 2003), written by Vacchi in the emotional aftermath of 11 September 2001 and the international conflicts that followed. After its première in Milan (2002), this piece was performed in Paris (2003) and Bruxellels, during Italy's turn of holding the presidency of the European Union. Ethical themes have great significance for Vacchi and they are evident in other compositions of his, such as Irini, Esselam, Shalom (2004) for voice, violin and orchestra, which deals with the theme of religious tolerance. Another similar piece was Dai calanchi di Sabbiuno for chamber ensemble, which was composed for the Commemoration of the 50th anniversary of the Italian Resistance (Teatro alla Scala, 1995) and which has been performed more than 100 times around the world, also in the version for full orchestra requested by Claudio Abbado. Ethical themes are still central in other recent works. In 2017 the melologue Veronica Franco was performed at Teatro la Fenice in Venice, about the great Venetian poet, courtesan, and proto-feminist who defeated the Inquisition of the 16th century with her free spirit. The Teatro alla Scala will be staging in May 2020 the premiere of Madina, Theater-Dance (whose text of Emmanuelle de Villepin focuses on the theme of terrorism), for actor, soprano, tenor, choir, orchestra and dance troupe with Roberto Bolle étoile, Was Beethoven African?, inspired by Nadine Gardimer's
