2003		G. Tate Midnight Lightning 97: My uncle was a freakin’ gangster who worked for Nicky Barnes’s numbers-running and dope operation in Harlem. So already I’m set up in a position to be a spoiled only-child megalomaniac gangster or just out of here. My only saving grace [...] was I loved playing the drums.
