One of the most masterful voices in Jamaican rocksteady, Ken Boothe sang with a mix of grace and grit whether he was contemplating love, heartbreak, or even politics. He voices frustration at inequality on the charged “Freedom Street,” and calls out discrimination on the harrowing “Is It Because I'm Black?” But his love songs are just as anguished, as on his cover of “You Left the Water Running” or his sleek take on “Brown Sugar.”
