Sleng Teng
Much has been said about this riddim and it's original version by Wayne Smith. Digital music had been made in Jamaica for a while, but it didn't really get accepted until Sleng Teng hit the charts. Check Prince Jazzbo productions from early eighties for pre Sleng Teng digi. (Horace Ferguson's Sensi Addict is a prime example). But Sleng Teng was the first "digi" riddim that hit big and it changed not only the sound but the whole business. Studiotime and expensive musicians was no longer needed to score big. This made way for a whole new generation of producers, musicians and performers.
