Thousands of Caribbean expats know and love the man born Denver Silvera and rechristened with an acronym for Jamaican Artists and Music United with the Sound of America. Part roots-reggae disc jockey, part comedian, part motivational speaker, Jamusa fills his drive-time show (Wednesday 4 to 6 p.m., Thursday and Friday 3 to 6 p.m.) with laughter, high jinks, and loads of great music. His love for Motown ballads and the romantic stylings of some of reggae's more genteel artists -- Freddie MacGregor, Luciano, Beres Hammond, Maxi Priest, Dennis Brown, Jimmy Cliff, Cocoa Tea -- gives the afternoon a dreamy glow. And Jamusa doesn't skimp on the "adaptations" -- reggae versions of pop songs like "Ob-La-Di, Ob-La-Da" or "Ain't No Sunshine When She's Gone." Hilarity ensues during Jamusa's call-in segment when listeners share home remedies for everything from diabetes and hypertension to whooping cough ("Vinegar an' honey!") or just laugh, reminisce, and swap stories about favorite songs, high school teachers, or childhood games. As a dispenser of sage advice --"A chicken dinner cya'an make up for broke eggs, yuh know!" -- Jamusa has no peer on talk radio or any other radio, for that matter.
