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 was a &' featuring 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 fails to launch the career of the band outside Brazil and the band remains an active, if elusive, act. 1999's Live Terrorism features the Ultimatum material as a bonus.
