Word reaches The Scala in Kings Cross on Thursday the 18th November. If you could pick four acts to represent the diversity, creativity and open-mindedness of the so-called American "underground hip hop", you could do a lot worse than these four. First up is Busdriver, taking the Left Coast school of fast rap in a whole new direction .Beans formally of Anti-Pop Consortium. Mike Ladd, the author of a succession of genre-blasting records, and one of the most forward-thinking figures working in hip hop. Rob Sonic, spilling out spiky, heartfelt and emotional lyrical intelligence with harsh, blazing sounds of the El-P school of production. A unique collaboration between four of the best and most respected independent labels in the world. Tickets from here.
