"By the time of this release - his fifth overall, and first two-record set - Hayes had firmly established himself as a progressive soul artist. His stretched-out and well-developed R&B jams, as well as his husky-voiced sexy spoken "raps," became key components in his signature sound. Black Moses not only incorporates those leitmotifs, but also reaffirms Hayes abilities as an unmistakably original arranger. Although a majority of the album consists of cover material, all the scores have been reconfigured and adapted in such a fundamental way that, for some listeners, these renditions serve as definitive".
