It’s been too long since anyone was able to bring this much soul and heartblood to progressive rock, a medium that has been left cold and dry by a misguided focus on technical show-offery. But by entangling the music they love township blues, fringe jazz and renegade dub into the DNA of prog, BLK JKS have provocatively pulled afro-futurism into a new century. After Robots has all the ingredients of a party record but this is not party music. It’s at times disorienting and overwhelming, but it always maintaining a cool, alluring mystique.
