Italy is a European country, an has had a long relationship with rock and roll, a style of music which spread to the country by the early 1960s from the United States. The earliest Italian rock bands appeared during this period, playing mostly strict covers. The first distinctively Italian singer-songwriter was Piero Ciampi, whose style was reminiscent of the French chansonniers. The United States and United Kingdom during the 1960s were in the midst of the psychedelic rock boom, and the field produced Italian psychedelic bands like Mario Schifano and Le Orme. After the 1968 student riots, many young, educated Italians began to identify with the counterculture which was flourishing in the US and UK; in contrast to those countries, however, Italy had little in the way of a rock tradition, though students remained very familiar with classical composers like Bach. The result was an influx of classically-influenced rock bands which fit right into the international move towards progressive rock. Italian progressive bands include Premiata Forneria Marconi, Banco del Mutuo Soccorso, Celeste, Reale Accademia di Musica, Saint Just, Goblin, Jacula, Devil Doll, Latte e Miele and New Trolls. Some bands, like Osanna, Area, Perigeo and Arti & Mestieri, fused progressive rock with jazz. Il Balletto Di Bronzo's YS is one of the most discussed Italian prog albums, with some calling it trash and others extolling it as one of the greatest progressive albums ever made.
