"The inventive record producer and vocalist Lee "Scratch" Perry was involved in every musical shift of note in his native Jamaica, from the rhythm and blues that pre-dated the arrival of ska in the early 1960s through the slower and more spacious rocksteady style that appeared mid-decade and, of course, the frenetic sound of reggae, which he helped to birth as an independent producer during the late 1960s. Operating as "The Upsetter" from his base in a downtown Kingston record shop, Perry found his greatest success with instrumental music during this phase, the organ and saxophone re-castings of standard vocal issues proving exceptionally popular overseas." - David Katz
