Born in Harlem section of New York City, Jackson was trained as a gospel singer from an early age, singing at the White Rock Baptist Church of Harlem.[5] There he met Paul Laurence, who would later become his record producer and songwriting partner. After completing school, Jackson joined Laurence's group LJE (Laurence Jones Ensemble) and played the New York nightclub scene. During the late 1970s, Jackson moved to the West Coast and sang lead with the band Mystic Merlin (with whom he released three studio albums, 1980-1982), but soon returned to New York to work with Laurence at the Hush Productions company.
