History
Robert Pettersson, Erik Viklund and Sara Almgren previously played in the punk band The Vicious. The lyrics were in English and they toured in the U.S. But when the drummer of The Vicious (André Sandström) left the band they had to find a new one and at the same point they decided to only sing in swedish. Erik took over the drums and Kajsa Bergsten joined the group on guitar. They released two 7"s and two full length albums before they decided to disband. According to Dennis Lyxzén (their record company manager), it was trouble in the band that got them to stop playing.
