Crass
After this members of Crass decided to be more serious about what they were doing. They decided to wear black clothes all of the time, whether or not they were on stage. This was so that no member of the band would be seen as the group 'leader'. They also made a banner that they hung up behind them when they were playing live. This had a logo on it that was made up of symbols like the Christian cross, the swastika and the British flag, as well as a snake with two heads that is eating itself. The meaning of this logo was the idea that "power will destroy itself".
