I suppose I shouldn’t be surprised anymore by the greatness of each new release on Analog Africa, but this Frankfurt label just keeps knocking me out. The latest salvo from Analog Africa’s proprietor, crate digger supreme Samy Ben Redjeb, is Afro-Beat Airways: West African Shock Waves, a bounty of post-Fela music cut in Ghana and Togo between 1972 and 1978. Redjeb has distinguished himself and his label not just by his perspicacity but also by his willingness to invest considerable time and energy tracking down the producers and musicians who made the incredibly rare records he finds. His hands-on approach puts him in a great position to tell the story of the music, or some fraction of it, in his voluminous, handsomely produced liner notes.
