Dre'Quan Priest
More hustler than gangster. Dealt on the street to cover the bills, but the music was always the actual plan.
Dre'Quan sold on the street to make ends meet, but Rockstar's framing is clear that dealing was the means and music was the goal. He reads as a promoter and an operator rather than an enforcer.
He is the connective tissue between Boobie Ike's recording studio and Real Dimez, which makes him the character most likely to pull the story toward the music industry side of Vice City.
