Jamaica was one of the first cultures to pioneer the concept of remixing. As a result, production level and sound system quality were critical to Jamaica's budding music industry. Since many locals couldn't afford sound systems in their home, listening to one at a dance party or at a festival was their entry into audible bliss. Writer Brougtton and Brewster's book "Last Night a DJ Saved My Life" states that sound systems were a product of Jamaican social lifestyle. The success of music wasn't just in the hands of one person anymore, it was a factor of the DJ, speaking poetic words to the audience, the Selector, harmonizing beats in an aesthetically pleasing way, and the Sound Engineer, wiring the sound systems to handle deeper and louder bass tones. Music became a factor of many elements and the physicality of that sound was a strategic puzzle left for musicians to solve.
