O Terço was formed in 1969 as a rock band. In its several formations after disbanding, added more and more pop elements to its sound, flirting also with progressive rock, but always kept its alternative status. This release is a tribute to the influential Brazilian rocker
Raul Seixas. In some tracks, they manage to keep a strong rock pulse. In general, a correct tribute with
Raul's hits "Sociedade alternativa," "Gitâ," "Mosca na sopa," "Metamorfose ambulante," "O trem da sete" and others.
