19. Augustus Pablo, 'East of the River Nile'
Dub music might be the most accurate-ever musical translation of stoned brainwaves. In the hands of Augustus Pablo, who transformed his signature instrument, the melodica, from kindergarten singalong helper to the sonic equivalent of an indica-packed ice bong, dub reached its most sublime heights. This instrumental set is his chill-out masterpiece, with productions by dub's two grandmasters, King Tubby and Lee "Scratch" Perry, along with grooves by a Seventies reggae A-team and occasional vocal fragments that surface like half-formed thoughts before slipping away again. Potent.
