The Sound System in Jamaica, in the beginning consisted of 3 crews lead by Coxsone Dodd, Duke Reid and Prince Buster. Most of the innovations were developed thorugh competition with each other, however shooting up a sound system if it had better music wasn't their first innovation.

The sound system began life as travelling record stores on the island nation. They would stop and play music to attract crowds, this eventually grew to market and sell alcohal. Sound Systems are most likely found in Dancehalls outside, mainly to accomodate more people, sell more booze, and so that sound clashes can occur.

Here were born the origins of Ska and Reggae
