Bob Marley in 1980.
the wailers, a band that was started by bob marley and in 1963, are generally agreed to be the most easily recognised group worldwide that made the transition through all three stages — from ska hits like simmer down through slower rocksteady; and they are also among the significant pioneers who can be called the roots of reggae — along with prince buster, jackie mitto and several others.
Some of the many notable Jamaican producers who were highly influential in the development of ska into rocksteady and reggae in the 1960s include coxsone lee scrath perry leslie kong duke reid joe gibbs and king tubby. Another early producer was chris blackwell who founded island records in Jamaica in 1960, then relocated to England in 1962, where he continued to promote Jamaican music. He formed a partnership with trojan records, founded by Lee Gopthal in 1968. Trojan released recordings by reggae artists in the UK until 1974, when Saga bought the label.
