This was the heaviest album Legião Urbana released during its existence. The only one which can in fact be classified as Punk rock. Two of the songs, "Conexão Amazônica" ("Amazonic Connection" – censored to contain heavy texts about drugs traffic and its routes by Amazon, and critical intellectuals.) and the Dylan-esque "Faroeste Caboclo" – the latter with 168 different lines and ten minutes long – were censored because they contained what was then considered obscene content. "Faroeste Caboclo" was a huge success, nevertheless. Others, such as "Que País é Este?", "Eu Sei" ("I Know"), "Química" ("Chemistry"), "Angra dos Reis" (a reference to a homonymous nuclear power plant that exists in Brazil) and "Mais do Mesmo" ("More of the Same") were hits.
