The track "Indo com o Tempo" makes a reference to his cocaine addiction, in the words "fase negra" (dark chapter).

Fans had been asking me for an album with original songs, but I spent the last five years reflecting about changes that occurred and making music slowly.

Jotabê Medeiros, from O Estado de S. Paulo, praised the album, giving it a three-star rank, stating that "bluesy guitars join the zabumba and the accordion and the manure mushrooms mix with the memories of the LSD in an album that would invent the career of a popular hero.

[5] Cristiano Bastos from Rolling Stone Brasil also gave it a 3/5 star rank and stated that "in Sinais dos Tempos [...], he is back to 'himself'.

That is, an outstanding artist, capable of creating inspired songs like 'Indo com o Tempo', 'O Começo da Visão' e 'Rio Paraíba'"[6] All tracks are written by Zé Ramalho
