Journalist Kevin Powell interviewed Tupac Shakur several times for Vibe magazine back in the 90s.
He just released his memoirs, The Education of Kevin Powell, and to promote them he's revealed for the first time audio of Tupac -- who was in prison for sexual assault at the time -- discussing the incident at Quad Studios in Manhattan in which he was shot.
