Although some people don't consider this album as the last one of the band (Mutantes had released another album in the end of the same year formally as a Rita Lee's solo album), this was the highest point of the band. Mixturing lots of styles (one of the main characteristics from the band), they have written one of the most glorious pages from the rock history of all times. From songs as "Balada do Louco" (ironically, today it sounds as a Requiem for the brilliant leader Arnaldo Baptista) to the ravishing "Beijo Exagerado", from the psychedelic "Dune Buggy" to the beautiful CSN&Y vocals style of "Rua Augusta", from the Latin rythmics of "Cantor de Mambo" to the censored hard rock "A Hora e a Vez do Cabelo Nascer" (by the 70's Brazilian Military Dictatorship), this album is their main masterpiece.
