By the age of 15. David Rodigan was DJing at school dances and youth clubs. The infectious. crazy back beat of Jamaican Ska first captivated him as a teenager in the mid 60 s. it was a driving. energetic sound which he found impossible to resist. When the pace cooled down and condensed into Rock Steady David was equally enamoured because the sweet. aching vocal style of Jamaica s young stars could be heard to full effect.
