The streets of Southall are alive with the sound of music…low slung, drop top BMW's cruise by blasting hard core rap, uk garage, R'n'B and bhangra! The kids playing out know all the words to every song, be it Busta Rhymes, Ashanti or Punjabi MC. In this suburban corner of West London sitting concentrating hard behind the desks is producer Rishi Rich, the man behind smash hit singles from Mis-teeq and Craig David, with further tracks due this year for Mary J Blige, Sugababes, Liberty X, Ricky Martin and Britney Spears.
