Antonio Russolo (1877–1943 Antonio learned music early through his father, who successfully prepared him and another brother, Giovanni, to pass the entrance exam at the Milan Conservatory. This Futurist musical concept, which was introduced by F.T. Marinetti, sought to avoid imitating the sound of everyday life by stylizing sonic materials so that it loses its original sense; acquiring a new aural sphere in the process. A record made by Russolo in 1921 is the only surviving sound recording that features the original intonarumori. It includes the pieces, Corale and Serenata, which combined conventional orchestral music set against the famous noise machines. This music was released in 1924 on a 78 rpm record. In these pieces, Russolo used the intonarumori as underlay. The sounds made are described as tunes disrupted by growls and low-pitched electrical interference. In the same year, Russolo's compositions were conducted during a concert organized by F.T. Marinetti at the Théâtre des Champs-Élysées. The program included four of Russolo's work along with two compositions of Nuccio Fiorda.
