sentences:  All of the songs on the album marked a stylistic shift in De André's lyrics, which became more poetical, more complex and less immediate than anything he released earlier.Reviewers at the time criticized the changes, and attributed them to the influence of De Gregori, who was known for writing stylized, not-readily-understandable lyrics which he was not always able to explain.Still, "Giugno '73" and "Amico fragile" were both written by De André on his own before he met De Gregori, and feature the same linguistic and poetical depth as the rest of the album.
