Hailed as “Jamaica’s Frank Sinatra,” Gregory Isaacs could express more with a sigh than a lesser artist could manage with 1000 words: As prolific as he was powerful, his aching vocals appeared on hundreds of releases. Not to be confused with 1979’s Cool Ruler album, this set bundles 1981’s excellent More Gregory LP with five singles ranging from 1978-84—most featuring the precise, bouncy one-drop beats of the Roots Radics band. On the joyous “Oh What a Feeling,” Sly & Robbie provide a spare, hypnotic drum and bass groove as Gregory revels in the pleasure of a reggae party.
