Sam Moore and Dave Prather were the ultimate soul duo; one a high-voiced wailer, the other a low-toned blaster. They came together in the mid-'60s to form a superb duo, singing tunes penned by soul's finest writing tandem, Isaac Hayes and David Porter. They made a host of great singles before ego battles broke them apart. This 50-cut, two-disc anthology not only has every song of significance, but plenty of obscure worthwhile items, like a "Stay in School" promo, some overlooked material done with the Dixie Flyers, and a couple of numbers cut by Moore as a solo act in the early '70s. The sound quality, annotation, and song sequencing are as outstanding as the songs themselves.
