Nice set of early versions of classic Wailers material, mostly produced by Lee Perry, but some of it produced by Marley. In some ways, though these are not the most well known versions, they're the definitive ones. Great easy skanking takes on "Lively Up Yourself","Small Axe", "Duppy Conqueror", "African Herbsman", the Curtis Mayfield tune "Keep On Movin", "Sun Is Shining" and "Kaya". An essential portrait from the formative years of reggae.
