David Rodigan's unlikely career as a reggae broadcaster and DJ has developed in parallel with the evolution of Jamaican music in the UK.

But standard versions of tracks don't cut it in a clash, where the true currency is 'dubplates' - versions of tracks recut, often by the original artist, with lyrics changed to praise the playing crew or diss
