After the debut album ''
L'uomo, they released the soundtrack for the film Milano Calibro 9. In 1972 they toured in Italy alongside Genesis. Their following album Palepoli'' (1973) is regarded as one of the finest hours of the
Italian progressive rock movement, characterized by a wild composition fantasy which mixes
Neapolitan and
Mediterranean sounds with modern progressive rock elements, such as the extensive use of electric guitar and
mellotron. In 1974, despite strife amongst band members, they released
Landscape of Life, which included participation from future rock and pop producer
Corrado Rustici, brother of Danilo and former guitarist of
Cervello, another artistic band hailing from Naples. The band disbanded but reformed in 1977 without D'Anna, who was replaced by keyboardist Fabrizio D'Angelo, while the bass role was taken up by Enzo Petrone. With this line-up they released
Suddance in 1978, to a large extent containing lyrics in the
Neapolitan language. Osanna disbanded again in 1979. ==Reformation==
