This 3-CD set focuses on the rich collaboration between The Wailers and production wizard Perry. The material, recorded in 1970 and 1971, much of which was previously unavailable except on bootlegs, features Perry's trademark atmospheric sound textures and his band The Upsetters. The Upsetters' playing, a cross between fluid South African-flavored mbaqanga and the driving rhythms of American R&B, paired with the soaring falsetto harmonies of Marley, Bunny Wailer and Peter Tosh, forges an aesthetic at once innovative and familiar.

Marley's voice is as beautiful and soulful as ever, and the music has a freshness and vibrancy much of his later work lacks. About half the 64 tracks are vocal takes. These, for the most part, are excellent. Some, like the groovy "Soul Almighty," the lilting "Stand Alone," and the ganja-tinted sway of "Kaya," are cause for celebration. The other half of the set is primarily instrumental, alternate versions of the main tracks, with additional studio treatments by Perry. As a cultural document, and as a sampler of great, utterly original music, this collection merits a listen from anyone, and is indispensable for Perry and Marley fans.
