The Rio band has existed under the moniker since 1982. Following a split LP called Ultimatum in 1985, the Brazilian boys demonstrated a continuing penchant for releasing thrash metal dealing with social issues. The second LP was released in two different versions to attract a wider audience. The band's first release outside the country featured two tracks from this album through the Swiss Flight Nineteen Records. This after the band's deal with SPV USA fell through because of that label's bankruptcy. A later deal with Wild Rags failed to launch the career of the band outside Brazil and the band remained an active, if elusive, act. 1999's Live Terrorism featured the Ultimatum material as a bonus. The band split up in 2001.
Antes Do Fim was rerecorded and released as Antes Do Fim, Depois Do Fim in 2005. Dorsal Atlantica had a movie called Guerrilha! in 2016. The movie was based on the band’s return in 2012. There was also a graphic novel about the history of the band (written and drawn by Carlos Lopes) which was out soon. Moreover, the band was recording a new album that merged Brazilian music with the band’s style.
Claudio and Carlos are brothers.
