In June 1971, PFM entered a competition-cum-music festival called the first 'Festival d'Avanguardia e Nuove Tendenze' in Viareggio, which they won, along with Osanna and Mia Martini. Later in 1971 the group signed with the Numero Uno division of RCA Records in Italy, and released their first single, "Impressioni di settembre"/"La carrozza di Hans". It received wide recognition as the first Italian hit record to feature the synthesizer. The group still regularly performs both songs. Flavio Premoli also did a special demonstration of the capabilities of his Minimoog during a PFM television performance broadcast by RAI.
