Soul Jazz Records’ new Boombox 3 continues their story of the first rap records to be put onto vinyl. It is a jam-packed collection of original independent ‘old-school’ hip-hop! After the explosion of hip hop in the parks and clubs of The Bronx in the mid-1970s, it was in Harlem where the first rap records emerged at the end of 1979 - an avalanche of superb rap tracks released on small independent labels all trying to capitalise on the success of ‘Rappers Delight.’
