The Treacherous Four Fantastic Breakout Tour 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 American so-called "underground hip hop" right now, you could do a lot worse than these four. First up is Beans part of the seminal Anti-Pop Consortium, whose latest album, "Shock City Maverick," shows an artist at the very top of his game. Mike Ladd is the author of a succession of genre-blasting records, establishing himself as one of the most forward-thinking and inspirational figures working in Hip Hop. Rob Sonic is Def Jux newest recruit. Spilling out spiky, heartfelt and emotional lyrical intelligence with harsh, blazing hip hop of the El-P school of production. Busdriver is the only MC from Los Angeles rather than New York. Taking the Left Coast school of fast rap in a whole new direction. A unique collaboration between four of the best and most respected independent labels in the world. Tickets from here.
