Many people think Bob Marley burst onto the international scene in 1974, but in fact he'd been a potent force in music in his native Jamaica since the '60s. These recording from the years 1968-1972 were formative ones for both reggae and Marley, where the Sound was forged from older island styles like ska and rock steady and American soul and country music. On this four-CD set, you can hear the proud, declamatory yet warm voice of Marley telling the world to "Lively Up Yourself" while commenting on the injustices of the world ("Go Tell It on the Mountain," "Duppy Conqueror," and "Fussing and Fighting"). During this time, the Wailers collaborated with Jamaican studio wizard/madman Lee Perry, one of the most inventive producers in or out of reggae. (The Clash, Tricky, and Squarepusher are among those heavily influenced by Perry.) These recordings don't have the polish of those of the '70s Island years, but the restless spirit and the fires of youth are here in abundance. This is a must for hard-core Marley and early reggae fans.
