After their first album, Dolce Acqua, from 1971 and their memorable TV presence at Sanremo music festival gave around mid-1972 Ivano Fossati suddenly had to leave Delirium for his military service, later to pursue a solo career that’s still successful today, even with a lighter (but always full of jazzy and ethnic influences) kind of music.
His replacement was Englishman Martin Frederick Grice (from Boomerang) who, along with the ever present flute, was also a brilliant sax player.
With this renewed line-up they released their second album, Lo scemo e il villaggio, still with some jazz influences and a stronger use of sax by the new member Grice, with the evident lack of a role singer in the band, all members taking the lead singer role. The track La mia pazzia is the closest to first album’s style.
