Perhaps no innovations have been as far-reaching as the set of boundary-smashing experiments that a small group of producers performed on multi-track recording machines and mixing desks in a handful of Jamaican studios throughout an astonishingly creative period almost 50 years ago. These pioneers created not just a vast trove of still-exhilarating recordings, but completely reinvented how a recording studio could be used, what a producer was able to do, and what listeners expected from music. – BBC
