The music on the album features typical jungle characteristics including influences from ragga, dub and dancehall, cut-up breakbeats, rude boy motifs and lyrics of urban alienation.

"[2] New York Magazine meanwhile described its influence from hip hop and "dancehall, dub and techno music that's distinguished by a frantic speed, a deep, detached bass pulse and a staicky surface of radio sound bites and unintelligble ragamuffin-style vocals," citing the genre's similarity to "early punk rock–at least in its tempo, noise levels and desired effect on the more conservative segments of British society.
