 In the mid-1980s, digital instrumentation became more prevalent, changing the sound considerably, with digital dancehall (or "ragga") becoming increasingly characterised by faster rhythms.In the early 1990s songs by Dawn Penn, Shabba Ranks, Patra and Chaka Demus and Pliers were the first dancehall megahits in the US and abroad.Other varieties of dancehall achieved crossover success outside of Jamaica during the mid-to-late 1990s.
