Gangsta’s Forbidden System is a sound system themed event organised by Beijing event team "Provocation". "Sound System is a cultural phenomenon originating in Jamaica that combines a powerful matrix of speakers, DJS and MCS to create a unique musical experience. The influence of the sound system extends far beyond Jamaica and has left its mark on music scenes across the globe, from the punk and duet roots of reggae in the UK, to the HipHop culture and electronic dance music of the US, to various derivative styles in Africa and Latin America. At our Sound Systems theme party you can enjoy the musical styles developed by a variety of sound systems from roots to innovations, from traditional to modern."
