Sinais dos Tempos is the nineteenth album by Brazilian solo artist Zé Ramalho, the first released through his new and own record label, Avôhai Music, and also the first after four consecutive tribute albums. The track "Indo com o Tempo" makes a reference to his cocaine addiction, in the words "fase negra" (dark chapter). His son João Ramalho guest sings on the album. Ramalho said he wanted to release an original album in 2012 because it is the year in which the Mayan calendar ended and many people believe that this will be the end of the world.
