Corey Harris takes a decidedly anthropological and academic approach to the blues, deeply researching its variants and origins, and he's become adept at combining West African, Jamaican, and Creole rhythms with traditional country blues forms in a manner so natural that the cracks and fissures between now and then and between here and there never seem to show. This set finds him revisiting the many different approaches he's taken to the blues over the years, from solo acoustic guitar tracks to full-blown band-with-horn-section tracks, and he does it all with the same sort of slightly ragged, live feel, which is perhaps why Harris' performances always seem fresh and energized, even if the song he's singing dwells on weariness, pain, or injustice.
