Big D was brought into the group by his cousin Kool Keith as a hype man in 1988. Tim Dog became an unofficial member in 1989. In 1990, DJ Jaycee was added as a road manager and backup DJ. A former member, Rooney Roon, was fired following an assault arrest. Beat-boxer Rahzel was a roadie for the group early in its career. The group's work was associated with unorthodox sampling, polysyllabic rhymes, and bizarre lyrical imagery.
